Science Toy
Name of product:
Slinky SpringIt's the Best Toy Because...
It's gravity in action!
My Review
It works best if you've a long straight stair, but even a short one or a series of table/chair/box works... set it up just right and you get gravity working visibly every time, stepping its way down the stairs. You get exercise going up and down the stairs repeatedly too.
Not suitable for a child with tendency to swing things around violently.
