An egg inside a mesh bag can be seen and then removed. It vanishes fro your hand and then re-appears!
Take a close look at the bag. The egg is inside a secret compartment. If the egg is not then take a moment to set this up. There is a velcro tab at the top of the bag near the opening. Gently pull on this to open and place your egg inside. There is a secret compartment where the egg can live. When you tip the bag upside down the egg falls behind a secret black curtain, inside the bag.
This illusion is that the egg has been removed from the bag, but it has not. It slides up and down behind the black secret curtain.
Do not forget that the bag has an inner secret hiding space. The egg can vanish all by itself.
