Start with the hidden bookcase door hardware if he has a wall and a weekend, and the electric fire bellows if he only has a fire pit. Skip the head-up display unless his car is old enough to lack one; newer dashboards already do this.

A sheet of LEDs that sticks to your back windshield and dances to whatever's playing. You can dial the sensitivity down until it stops reacting to your own turn signal. It rolls up for storage. You'll want that in March, when the novelty dies and you'd like to see out of your car again.
Hinges only. There's no door in the box, so somebody in your house needs to own a saw and a realistic sense of their own abilities. The pins hold 300 pounds and sit flush, so the bookcase reads as a wall until you shove it. Murphy Door includes zero instructions.
Two flying saucers, each with a ray gun that pulls straight from the pool. No refilling, no truce, no natural stopping point. Somebody designed this knowing exactly what it'd do to your Saturday and shipped it as a two pack. They're ride-on sized, so nobody gets to claim they're too old.
Plugs into the OBD II port that every gas car sold here has had since 1996, and throws speed, RPM and coolant temperature onto the glass in front of you. Use the anti-ghosting film in the box if your windshield is laminated, or you'll read two speeds at once. It's 5.5 inches, in color.
A food grade liner that drops into a regular bathtub and fills from the faucet, holding 100 gallons behind a seal for up to 16 weeks. It all depends on one behavior: setting it up before the storm rather than during it, once the faucet has stopped being a faucet.
450 watts, three modes, and the one that matters stuffs every bubble full of fog so it pops into a small cloud on the ground. Tanks hold 18 ounces of bubble fluid and 10 of fog. The remote reaches 40 feet. Depending on your fence, that covers your yard and a chunk of the neighbor's.
A Japanese bar trick, boxed for the kitchen counter. The unit spins a glass until the head freezes into a dome with the texture of soft ice cream, and that cap seals the beer underneath so it stays cold to the last sip. Runs on four C batteries. The glass isn't included.
Marketed to referees and search parties, bought mostly by people who want a conversation to end. The rating puts it past a jet engine at close range, a number worth reading twice before you test it indoors. There's no pea inside to freeze or jam. Hearing protection isn't included.
Drop a warm can in, pack ice around it, press one button. Spinning drags every drop of liquid past the chilled wall, so a minute does what an hour in the fridge does. Rotating a soda sounds like the worst idea available, but the spin's gentle enough that nothing erupts on opening.
Cast metal, officially licensed, sized so the ears clear a paperback. The listing carries an unusual warning: lightweight books only. Nine hundred years of holding a galaxy together, undone by a hardcover dictionary. Put it at the end of a low shelf where the fall would be short.
Feed in a regular roll and it chops the sheets into wet pellets, then fires them about thirty feet. Water rather than spit, biodegradable, and the packaging promises no stains, a sentence that tells you what the first question was. One roll makes several hundred rounds. No batteries.
A one to one replica of the board from the second Back to the Future movie, 28 inches long, with a strap for hanging it on a wall. It doesn't hover and the listing says so plainly. What it does settle is the argument about scale. The prop turns out smaller than memory insists.
The shirt has a ruler printed down the front, starting at the collar, so the wearer can stand at a mirror and settle the question. Cotton, standard fit, military green. Whoever gets this will check it monthly and report the number to people who didn't ask.
The Pocket Shot swaps the forked stick for a circular pouch, so the whole launcher packs down to about the size of a drink coaster. A hammer handle adds leverage and the arrow cap turns it into a short range bow. Three pouches at different draw weights. Aim at hay bales, not fences.
Headlight fluid isn't a thing. This bottle looks close enough to real automotive fluid that somebody who has never opened a hood will take it at face value. It's sold to be given to one specific person, and you thought of them before you finished this sentence.
A fan the size of a flashlight that pushes a steady stream of air into a fire that won't catch. Triangular so it doesn't roll off a rock, with a flame retardant nozzle and a button that cuts out on its own. It replaces the part of camping where somebody lies flat on the ground blowing.
One liter of air, around 75 breaths at shallow depth, in a cylinder you can carry in one hand. Aviation aluminum, DOT certified, with a relief valve that vents before pressure becomes a problem. It's sold for hull checks and dropped keys. It isn't a substitute for training or a real tank.
A seven color thread blend, stitched thick enough to disappear against a treeline. Built for hunters and it works for them, but the second market is anyone who's ever wanted to stand still in a yard and be a shrub. Double stitched, so it sheds less than the cheap ones. Adjustable hood and waist.
Pull the trigger and 69 wands fire at once, thousands of bubbles a minute, with lights running down the barrel for no reason except that it's a bazooka. Nontoxic ABS, no sharp edges. A child will empty the bubble solution in about four minutes and ask for more. Buy the refill at the same time.
Strips of waterproof LED that mount along the board and cycle through seven colors and three brightness levels. Rated IP68, so slush and a full day of falling don't bother them. The maker claims visibility from over half a mile. On a night run that's safety. On a lift it's showing off.
A mesh sleeve that stretches over an open SUV door on an elastic edge, so you can sleep in the back with the windows down and the bugs out. A small awning keeps rain off the gap. No tools, and the listing names the SUVs it fits. Any rest stop turns into a campsite.
A metal wick in a fuel reservoir the size of a thumb: strike it on the case, it lights, blow it out, put it back. Fill it with lighter fluid and it keeps going. Five in the pack, half an ounce each. It's a lighter that behaves like a match, and people ask about it.
The shaft is hollow and holds more than you'd expect. A terrycloth towel clips on for privacy while you appear to be studying a putt. Leak proof cap, sold with a straight face. It started as a gag for slow foursomes and long back nines, and it turned into a real product for the same people.
Fifteen tiny decals for the blank switches every dashboard has, the ones the manufacturer left in for a trim level nobody bought. White print on clear vinyl, three quarters of an inch square. Now the blank is labeled. It still does nothing, but it's honest about it now.
The Manneken Pis, the small bronze boy of Brussels, as a drink dispenser: fill the reservoir, press the button, and he pours. It's been a bar joke since before most of its buyers were born and it still gets the reaction. Holds liquor, pours anything, rinses clean.
A small Roman soldier whose armor is the grater. Hold him by the legs and run parmesan down his chest. The steel is sharp enough for hard cheese, chocolate and citrus zest, and he rinses under the tap. Peleg Design calls him the Gratiator, and yes, that name was the reason he got made.
294 laser-cut wooden pieces that assemble into a marble lift with a hand crank, and once built, ten marbles ride to the top and roll back down through the city. The instructions are good and the build takes an afternoon. Then it sits on a shelf and gets cranked by everyone who visits.
Cold, the mug shows Kirk and the landing party standing in the transporter room. Add hot coffee and they dematerialize, leaving the pad empty. Cools down, they're back. It's from the Unemployed Philosophers Guild, who've been making this exact kind of joke for thirty years. Hand wash it.
A Moai on a nightstand base, with a slot across the nose that holds most frames, from thin metal to chunky acetate. The base takes a phone. It's a spot for the glasses that otherwise vanish before you can find them, and the head looks better wearing them than you'd guess. Stone-look resin.
A sealed glass bottle of camphor solution on a wood base. The crystals inside grow, cloud and settle over the day, and 19th-century sailors read the patterns as a forecast. Admiral FitzRoy carried one on the Beagle. Whether it beats a phone is not the question; it's a slow, changing object on a shelf, and the maker includes a card explaining the old interpretations.
A resin bear cub, 22 inches tall, standing on a stump. One paw holds the roll up for you, the other covers his nose. Three spares stack on the post behind him. It's cabin decor for people who don't have a cabin, and it says exactly what it's for from across the room.
An infrared sensor watches 60 feet of yard, and when a cat, a raccoon, or a neighbor crosses the line, a sprinkler fires a short burst of water at it. Two or three cups per shot, no chemicals. It's sold as humane pest control and it is, but it doesn't check species before it fires.
Four inches of antique-style key that opens bottles. It lives on a keyring and nobody notices it until it's needed. An ounce and a half. The disguise is good enough that people ask what it unlocks, and telling them is the best part.
A rechargeable, gun-shaped Tesla coil that throws a visible electric arc from the tip and lights a fluorescent tube through the air. There's a voltage meter on the side and a gold-plated panel on the front. It's a science demo with a trigger. Keep it away from phones, pacemakers and anyone who hasn't agreed to be in the room.
Six IN-14 nixie tubes, new old stock from Soviet-era warehouses, glowing orange in a case. The tubes plug into sockets instead of being soldered, so when one dies in a few years you replace it. A motion sensor turns the display off when nobody is in the room, and that's what stretches their life. It's the most expensive thing on this site and it looks it.
Pour hot coffee in and the black glaze turns clear, revealing the artwork underneath. It cools, it goes black again. Thermochromic glaze, eleven ounces, dishwasher safe. The reveal works exactly once per person, so pick who you hand it to.
A Stirling engine turns a temperature difference into motion: heat one end, the air inside expands and contracts, the piston runs. This mirror-polished model comes with a small alcohol burner and a built-in voltmeter that reads what the spinning flywheel generates, enough to light the included LED. It's a working demonstration of an idea from 1816, and you can hear it across the room.
Walk within 10 feet and the owl says something. Over 360 clips are built in: dad jokes, sound effects, animal noises. No app, no Bluetooth, no pairing. Put it in a hallway, a bathroom, or the corner of a shop and it will ambush everybody with the same enthusiasm. Whether it's charming depends on how many times you've passed it today.
