If your school has banned fidget spinners, you’d definitely get in trouble if you brought this one in…
TheBackyardScientist has built his own fidget spinner – and has strapped rockets to it!
The rockets help it spin at 88 turns per second for over two minutes. It takes two attempts to get the spinner going as fast as it can and looks pretty dangerous.
He made it by cutting a piece of aluminium using a special tool and then, using clips for pipes, attached three rockets.
The three rockets work kind-of like fireworks, pushing the spinner around!
Don’t try this at home!
