Magic Tricks

It's a DIY video about 11 minutes, CONSTRUCTING the gimmick and showing how it works .
A poor explanation and language, but you'll understand anyway.
The video is ok but not more than that , because he needs to shot with more zoom in , the stuffs are small and needed to zoom in, if you're over 40 years older you might understand what I mean.
In order to build the gimmick you need to purchase stuff from your hardware store and a stuff that it could be you should have at your house if you're a DIY user, and it shouldn't be a difficult problem.
He didn't explained how much liquid you need to fill the can and he didn't show the gimmick working with a liquid inside, I guess you need to experiment by your own self. Other than that it has a great potential in real life and practical.
