Slinky Stairs Spring also named as Rainbow Spring is an extremely soft spring. It is usually made of thin spring wire or plastic
with flat rectangular section. The spring stiffness of r Slinky Stairs Spring is about 1% of the ordinary spring. When it is not
stressed, all coils are in contact with each other, so it can only be stretched or extended other than compressed. Place the two
ends of the spring on the palms of both hands then bend it into an arch, and then move the left and right hands up and down
alternately. You can observe the rapid rolling of the coil from left to right or from right to left alternately. The changing
colors looks like the beautiful rainbow in the sky, so the Rainbow Spring is named.

The most unique skill of Slinky Stairs Spring is that it can automatically go down the stairs. Place the two ends of the spring on
the two steps at different heights of the stairs respectively. After letting go, the higher end of the spring will suddenly jump,
bend and fall to the low step, and then the other end will jump up. Repeat this process and keep falling in the way of somersault
until the bottom of the stairs.
