Water Rocket Challenge Water Rocket Challenge

Aim for the sky in our annual Water Rocket Challenge, which sees hundreds of participants, from school teams to adults, battling it out to become champion.

From school teams in the afternoon, to company teams, adult enthusiasts and youth groups in the evening (as well as rocket-making workshops), the NPL Water Rocket Challenge is a great day out which sees teams of rocketeers take to the skies with their own water rockets!

The 2018 Water Rocket Challenge will take place on
Wednesday 20 June, so save the date!

Company teams

For company teams, this the perfect team-building exercise – building and competing with rockets!

For the first time, NPL Water Rockets are running the 'Company Challenge'. Teams of up to six should arrive at the sports field at 18:00 and will then have 90 minutes to open a box and follow enclosed instructions to create a rocket. No other equipment or prior preparation is required, but the Rules & Information should be read beforehand. Company teams will then compete in the Main Challenge against others, and there will be a Company Award for the best achiever in this group. With just 10 spaces available, we encourage early registration. Afterwards, teams may keep all equipment they use (except pumps) and are welcome to register as regular teams in future years. And teams are welcome to bring along family, friends and co-workers to spectate and cheer on.
