Goliath Boomtrix Multiball Kinetic Metal Ball Chain Reaction Stunt Kit - Fun - Educational - STEM

Cadeau à mon petit fils

I got this set for my 9 years old son. He enjoyed constructing it and had fun with creating the bounce pattern.

Assembly instructions are really vague, mostly consisting of a few images of partially assembled pieces. I figured it out, but wouldn't expect a kid to do it. There's enough wobble in the structures that the balls bounce differently each time. I'll adjust a trampoline placement and try again, only to find that he marble goes somewhere different each time. Satisfies when you get a good series of bounces, but it's not repeatable. How much patience does your kid have? This might teach them more or it won't get much use.

The media could not be loaded.  My boys (8 & 12) are really enjoying this! Right now it’s set up on carpet yet still super sturdy. You need a little patience to keep adjusting it till it’s just right. My son took the slow motion video for me to share here! I recommend it!

Bought as gift for 10yr old, challenging but great fun
