If your child already has the Wall Coaster Starter Set and/or the Extreme Stunt Kit, then this Crazy Stairs Add-On Trick Pack is perfect. Kids will get hours of enjoyment watching marbles slide down the stairs.

Each kit comes with 7 inches of stair track, which is designed to slow the marble down as it descends, moving from side to side as it goes. The Crazy Stairs kit is an addition to other Wall Coaster sets, which are sold separately. Either the Wall Coaster Starter Set or the Extreme Stunt Kit is needed before the Crazy Stairs kit is fully functional.

Invented by a 12-year-old boy, this action-packed kit is sure to provide hours of entertainment. This innovative set develops strategy, hand-eye coordination and spacial reasoning. It uses the basic laws of physics and gravity for hours of fun and excitement. The specially-designed coaster tack is created to adhere to most wall surfaces without leaving a mark. Best of all, the reusable tack allows you to change and re-design the paths whenever you want!

However, this kit should not be used on carpet or other porous surfaces, nor should it be used on wallpaper or newly-painted areas. It is recommended to test a section of track before setting up the entire kit.

Two marbles and a package of coaster tack are also included with the Crazy Stairs kit. This item is recommended for ages 5 and up.
