The Bongo Hat! A kid show magic classic!

You try a bongo hat on your volunteer but: 'Oh No! It's too small!'

So with a bit of magic, you make it larger....
...and larger
.... and larger!...lots of comedy as the hat changes colour and pattern with each 'growth', and finally reveals a picture of a green monster face!

The Bongo Hat is a great piece of kid show magic.
