Gecko Run Marble Run Twister Expansion Pack by Thames & Kosmos – Extra Stunt for Vertical Marble Run Starter Set; Fast, No-Mess Setup with Residue-Free Nano-Adhesive Pads for Hours of Creative Play

The ball was smaller than i anticipated but i still give this 5 stars because i am sure i just missed the measurements somewhere. Plus the track actually does stick to the wall and various other surfaces quite well regardless of how many times i have removed and restuck them (maybe 10+ times by now without washing the sticky pad). The ball glides through the curves of the track smoothly and so controlled its as if the ball and the track were magnetically attracted to eachother. The loop requires a good amount of speed to be able to get through but its not difficult to get the correct angle and there are ways to do it with a curve too. I will continue to play with this until my child is of an age this would be safe for…… :-)

I really think the fact she likes it is she can always redisign. As well as its allready picked up its up ha ha

Picture makes them look larger than what they really are tiny small

You is well constructed however it was difficult to make the pieces stick to our clean, dry, smooth walls.However I will say the adhesive did not damage our walls at all for the few pieces that did actually stick to the wall

Bought the expansion pack as well. Highly recommend male or female.

Love the features

The Gecko Run Marble Run Twister Expansion Pack by Thames & Kosmos is a fantastic addition to the starter set! I placed it on glass, and the nano-adhesive pads worked perfectly—easy to stick, no mess, and completely residue-free. The pieces are well-made and add an exciting twist to the marble run experience.My only complaint is that it didn’t come with enough pieces to fully explore its potential. However, when paired with the starter kit, it’s an absolute hit. I highly recommend getting the full set for endless creative play. Perfect for both kids and adults!
