This year’s “must have” – The Scientist Factory’s boomerang ball!
- Attach the rubber band around your hand and throw the ball as hard as you can.
- Can you catch it?
- Try to throw the ball with “wrong” hand.
- How hard do you manage to throw and can you catch it again?
- Use it to do tricks without it rolling away from you. The ball will always come back to you.
- The attachment device around the wrist can be adjusted to a minimum of 5 cm in diameter to a maximum of 6 cm in diameter.
