While I was having toast and coffee in the living room, my youngest sun wake up and came to me, saying, "Dad, do me a favor and help me create this." What he showed me was Piggy bank on the book. Strictly speaking, it a coin bank with a miraculous trick.
Take a look at the left picture. This is a saving box that my son and I made this morning. It was not a tough job and totally took about an hour. One thing that is really interesting to me is a ball of Pokemon in the white box. It looks like as if the ball is floating in the air, doesn't it?
This trick box is consisted of a hemisphere attached on a mirror and a cardboard cube with a window in the front side. The combination may be simple but the effect is beyond my imagination when the mirror is obliquely placed.
Another thing that surprised me was his ability to create something. Over years, I have helped my son with his craft homework during his summer vacation, however I have never felt his powerfulness regarding doing it yourself than ever before.
No wonder that my little son is evolving. Next year, I might not be needed anymore.
