No magic, just knowledge of the laws of physics and that’s it! Everything is very simple, it’s like a forgotten childhood toy “tumbler”. Make a similar ball and surprise your friends. He rolls very slowly along an inclined board and may even stop.
For this focus, we need:
• metal ball;
• plastic ball (from two halves);
• gel.
To begin with, we put our metal ball inside a plastic ball and fill it with gel to about half of the plastic ball.
Then you need to connect the two halves of the plastic ball so that they "slam shut."
To hide that there is also a metal ball inside the plastic ball, carefully paint the plastic ball with a marker.
That's all, our focus ball is ready.
