The box says for 5+ but I would think children far younger would puzzle as to why a ball dropped will bounce up to the same height, or why a ball bounced goes even higher and then exactly how high will it bounce when thrown onto the ground.
Even on grass I easily got it bouncing well above my head, on concrete it bounces far higher.
My neighbours pre-teen children were puzzled as to why a tennis ball or even a football needed a lot of downward force to get anywhere near the height of the moon ball.
The moon ball sent to me was blue and black around 6.5cm across and has a lot of little black circular indentations – over twenty - in the otherwise blue exterior. It has just a little give when squeezed and weighs 69grams.
I have no idea how the science works but I do know the amazement in a young child’s eyes.
At the time of publication the Moon Ball is available in Blue, Green, Purple, Red or Yellow from Amazon for £6.
Stomp Rocket 40000 Stunt Planes Kit
The unit I was sent is one of a range of such items. This needs more space than the ball above and while I tested it myself in a green area I was not able to see my neighbour’s children use it due to the current Covid restrictions.
Things such as this are used by teachers to explain a number of scientific principles. It is sold as suitable for age 5-12. Among the things teachers will use something like this to teach is Gravity, Force, Trajectory and the Power of Air.
In the box I was sent is the tri-legged stand 26x30cm, the ‘stomp’ foot 20x10cm hose to connect the ‘stomp’ to the stand and three slightly different 20cm tall rockets, these are described on the instruction sheet as Looper, Glider and Wildcat.
The back of this sheet teaches them other principles like wind. trajectory, force and aerodynamics and how to use them.
At the time of publication the Stomp Rocket 40000 Stunt Plane is also available from Amazon for £27.99.
