5. Rocket Launcher

3. Tornado Machine

Want to liven up your living room? Then build your own tornado machine, using the plans found here. Here’s what its creator had to say:

Can you build this? Yes! However, the design of this machine is more elaborate than it would need to be to just produce a vortex – it is meant to be put in your living room or somewhere else that requires it to look nice. If you follow the construction plans carefully and methodically, you will find that building this machine does not require a lot of work, and the results will be well worth it!

2. Vacuum Elevator

This home-built Vacuum Elevator is a simple yet “interesting way of lifting a small elevator cab”, perfect for any 2-3 story home.

When the piston gear depressurizes the area inside the cylinder above the vacuum elevator cab, the cab is then lifted by higher atmospheric pressure below the cab. The inside of the vacuum elevator cab always remains at the atmospheric pressure. As air pressure is lowered above the cab, the cab is lifted

1. One-Lane Garage Bowling Alley

Tim bought an old Brunswick A-2 pinsetter off eBay and made it into a one-lane bowling alley inside his garage.

I would assemble the pinsetter in the back room, knock out a whole in the wall when I was ready to assemble the lane which would extend out into the front room (the original garage), and in the winter, I could pack the lane away, cover up the whole in the wall, and park a car in the garage. Nobody would ever know there was a bowling alley in there
