Water to Wine Illusion Box

Have you ever wished that you could turn water into wine (or at least fruit juice). Well now you can with this magic mystery box. All you have to do is pour in water. Then inside the box a bunch of magic happens. Finally out comes a fine glass of wine. It is a simple illusion that uses water pressure and air pressure to switch the drinks. It can make for a fun party trick to amuse your friends.

Solar Power Tools

Solar power is a great way to get electricity out to a remote project site. One simple way to do this is to use a solar panel to charge the batteries of your cordless power tools. In this project, I am going to show you several ways that you can do that.

Unwashed Hands Alarm

You have probably seen signs in a restroom that tell people to wash their hands. But how often does that sign go ignored. Here is a humorous way to find out. In this project, I made an alarm that goes off if someone forgets to wash their hands when they use the restroom.

Personal Cooling System

Summer is hot. And we all need to find ways to cool down. So I built a thermoelectric cooling system that can mount to your wrist. A thermoelectric element acts like a miniature refrigerator. It can turn electricity directly into a change in temperature. By adding a heat sink, you can improve the efficiency of the cooler. This apparatus gets mounted to your wrist right above your radial artery. At this point there is a lot of blood moving near the surface. By cooling this point your blood helps to distribute the cooling effect over your whole body. It looks ridiculous, but it works.
