1. Suspending Water Without a Cup
The trick for this is everything is subjected to gravity. And the inertia allows it to stay in shape for a few seconds. Some people claim that this video is a fraud nevertheless, it's fun to try and if you can't do it, well, go on with the next video.
2. Home Made Projector
Well, this one is not really a home made cause it uses the OHP to project the colors from the flat screen. But somehow if you compare the price for OHP + Flat Screen with a Projector itself, i doubt that the OHP and flat screen will cause cheaper. Anyhow, it is an awesome manipulation of electronic devices and only those who has the passion to do it can do it. This projector only need a white screen and i think the resolution is great because they used flat screen!
3. Home Made Air Conditioner
With the weather approaching 36 degree centigrade in Malaysia, i believe this one is the most useful one. The only problem is whether or not you have the passion to sit in your garage trying to make this air cond in a hot weather. It uses water as the cooling agent and i doubt this home made a/c will produce carbon dioxide gas which is harmful to nature. In a way, you'll get a green air cond in your house with a very cheap price!!
That's it for today. I'm off to find another cool thing for you guys to know. Bye.
