Hyperlauncher Rocket Ball Factory Review

This review is our second project as part of Science and Engineering Week (14th – 23rd March). Over the weekend Callum and I had been very busy experimenting with The Hyperlauncher Rocket Ball Factory.

In the kit you will find:
  • 60g of Coloured Polymer
  • 3 Plastic Tubes
  • 2 Wooden Dowels
  • Protective Goggles
  • 1 Small Mould
  • 1 Medium Mould
  • 1 Large Mould
  • 1 Extra Large Mould
Before you start you must read the instructions carefully. This set is not suitable for children under 8 years old and even those over 8 must be supervised at all times because of the materials you are using. If used correctly they are safe and non-toxic but if not they can be dangerous.
The fun part of the set is making your Rocket Balls. They are very easy to make in 8 easy steps but this is where the safety instructions must be followed as this is the bit where you are using the materials.
  1. Fix all four moulds together
  2. Push a plastic tube in the hole in the bottom of each of the three smaller moulds
  3. Fill each of the three moulds with polymer granules – tap them to make sure that they are properly filled (make sure you have them on a tray to catch any spilt granules)
  4. Fill the biggest mould – tap it to make sure it’s full then push one of the dowel sticks into the granules making sure it’s in the middle
  5. Get a bowl of warm water. Make sure the moulds are pressed firmly together and then place them under the water for 30 seconds each – make sure you’re holding the moulds together as they will expand as they start to set
  6. You then need to push your plastic tubes up and down in each mould 5 – 10 times whilst counting to 60 seconds
  7. Open up the moulds, take out the tubes and leave the balls to dry
  8. Repeat step 5, 6 and 7 with the larger mould. Except leave the dowel where it is

Once the balls are dry you are ready to experiment – this is where your safety goggles come in


Callum really enjoyed making the rocket balls and was very happy when it came to the experimenting stage. As you can see from above he took it very seriously and wore his goggles as instructed to do so. The experiment involved seeing how high we could make the balls bounce. I won’t reveal our findings as this is really something you should try for yourselves but we had lots of fun and even had to search for the smallest ball when it went missing. You can vary the experiment by using fewer balls or placing them different size orders.
Overall, we had a lot of fun doing this project. It didn’t take us long to set up at all. The set is priced at £12.99 and can be purchased from Interplay. This is definitely a set I would recommend for any science fan.
