There is always something fascinating about making a track of falling dominos or a marble run, and one man has built for his son’s room one of the best marble runs we have ever seen!
As you will see in the video below, the track runs around the entire room near the ceiling, allowing marbles to go round and round and round for endless entertainment!
And if you fancy teaming up with your mum and dad to make something similar, the man has even place instructions online. Click here to find out more.
The only thing we would say is make sure you take all the marbles out before bedtime, as it may keep you up!
