Marble Run fun with Wall Coaster - an innovative marble run that attaches harmlessly to household walls!
This brilliant concept teaches children about angles, friction and gravity and the need to align pieces to ensure a smooth and fast marble run. The challenge can be heightened by taking the run around corners and by adding the Extreme Stunt add on.
Relax! The "tack" used to fasten the marble run to the wall is very similar to blue tack.
