Wrappable! This item can be beautifully gift wrapped.

Engenius Contraption is an award-winning flat-pack marble run that you assemble yourself.

This simply brilliant marble run is made of plywood, with all the parts coming laser-cut in sheets - just follow the simple set of pictures to push-fit them together. With a build time of 1-2 hours, assemble the spiral run and zig-zag before adding the electric motor. The marbles are raised to the top of the lift, descending down the spiral then down the zig-zag track...then back up to the spiral to start again, in perpetual motion. Winner of Gift of the Year 2019, fun and extremely satisfying to build and mesmerising to watch.

Excellent website, really unusual items. I bought the interactive T shirt as a 10th birthday present for my grandson, and he loved it. Delivery was very quick. I am a very satisfied customer and I'll be back.

Slimy, sticky slugs were winners

Bought a few gifts for the grandchildren ages 2, 3, 4 and 5 9two boys, two girls) - all were well received - but theslimy, sticky slugs were clear winners with them all - the younger ones squealing as they cautiously touched the sticky surface and the older ones play acting and 'scaring' the adults - and not just for five minutes"
