Blasts down the stairs, jumps from your hands, springs from the table tops and much more.

This is a pre-compressed spring that can perform a number of different tricks, most famously travelling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum.

It can also appear to levitate for a period of time after it has been dropped and makes spooky sound effects.
