3 reviews

If switched on this machine switches itself off. On, off, on, off — hours of entertainment.

The Useless Machine is a gizmo that turns itself off when you switch it on. But how? Is there a little stubborn person in the box playing a trick on you? Is it magic? No, it's a set of switches with a small motor and you can put it together yourself!

By building the kit, only you will know the secret of how it works. When you show it to your friends and co-workers, keep them guessing - after all, you built it so it's your secret! This version of the Useless Machine has been refined for a clean design and ease of assembly. There is no soldering required; all you need is a simple set of screw drivers and 30 minutes of time. 

Be aware - playing with the Useless Machine is highly addictive. Don't say we didn't warn you!
