This came from a magician’s estate purchase. No instructions. This is a very cleverly designed snake can as the lid to the can can be removed without the spring snake shooting out until the performer wishes it to happen.
Inside the Doritos can is another can with a metal barricade and sliding metal lever that is controlled from the bottom of the Doritos can. The spring snake is loaded into this inner can, the hinged barricade placed over the mouth of the can, and then the metal lever moved into position to hold the spring snake in place.
Once set you can load into the Doritos can whatever you wish.
How you proceed from here is up to you. But whenever you’re ready for the surprise spring snake appearance all you have to do is slide the metal lever with your finger to release the hidden spring snake from its hiding place.
Supplied with the pictured spring snake.
