There are plenty of Space Hoppers World Records to have a go at beating. We at http://www.space-hoppers.co.uk have been supplying space hoppers for such events since the very first record, as we have the highest quality (most reliable) product sold in the UK.
The last thing you need when about to break a world record is a failure from your equipment.
We have experience in both single hopper events and bouncing on mass. We can guide you through the process.
