In a previous video, I showed you how to make a PVC rifle that can blow holes through plywood decking. Well, some of my viewers asked if it could be converted to something a little more family friendly. Well, the answer to that question is “Yes!”. To make the cardboard rocket rifle, we’ll need a 1″ threaded PVC adapter, a 12″ section of PVC pipe, a cardboard wrapping paper roll, and of course… our completed CO2 Cartridge Rifle from the [...]
In my previous video, I showed you how to make a battery out of a potato. The truth however, is that the potato doesn’t make the electricity, the copper and zinc do, and all you really need is an electrolyte between them. To make a penny battery, you’re going to need zinc washers, copper pennies, a small section of cardboard, electrical tape, a small glass, some white vinegar, and multimeter would be great if you happen to have one. Step [...]
To make a potato battery, you’re going to need a potato, some copper pennies, zinc washers, some test leads, an LED or other device to power, and a multimeter if you happen to have one. Now, if you don’t have any pennies or washers, you could substitute copper wire or galvanized nails for example. The first step is to cut our potato in half, then make some slits in the top for our electrodes. Insert our penny cathode and washer [...]
The parts list for this and other projects can be found at TheGeekPub.com. In order to make the faucet appear to be oozing, we need to remove the rubber section from our pacifier. I first tried cutting it with a pair of dikes, but that didn’t work very well. However, I realized simply squeezing the holder with a pair of pliers popped it right off. Then, you can just gently pull the rubber section out. The next step is to [...]
David from Awesome Airguns demonstrates the CO2 Cartridge Rifle.
So I have this little Umarex CP99 pistol. It looks like a Walther .22, but its really just a CO2 powered BB pistol. I spend a lot of time shooting it at tin cans in my back yard and its a lot of fun, but I end up with a lot of these. And that got me thinking, “Could I shoot these?” Be sure to checkout TheGeekPub.com for the parts list for this project. As with the water balloon cannon, [...]
You’ve probably seen Magic Sand at your local gift shop or magic store. Today, I’m going to show you how it’s made. The first thing we’ll need is a baking pan wrapped with aluminum foil, so that we don’t damage it. Be sure to wrap it around the edges to completely protect it. The second thing we’ll need is some dry sand. I bought this bag of hermit crab sand at my local pet store for about $3 bucks. And [...]
There’s nothing more frustrating than to want to have a glass of wine when the bottle has yet to be chilled. What do you do? Add ice to it? That works but it leaves your wine watered down. Heres a better idea. Get some grapes, put them in a bowl and then keep them in your freezer. Then next time you want a glass of wine and the bottle hasn’t been chilled, just add some frozen grapes before you pour [...]

The main item we’ll need is a small plastic container. I got this one at my local big box store for about $5 bucks. The second item we’ll need is a small computer fan. I found mine in my junk drawer, but we’re going to need to cut off these tabs so that we can mount it to lid of our box. I used my Dremel with a cutting disc. There’s several tabs to cut off, so it takes some [...]
