interesting art

The art that I recommend is a switch
There is the switch using the corrugated cardboard like this photograph, too

Even Japanese TV has it broadcasted
I will be pleased if I show a small child it
I want to make the once, too
There is the switch using  water , too
The switch which I like is a switch using the corrugated cardboard

I do not get tired even if I watch this animation  several times
I was impressed to see this

Everybody please look by all means
