5 HOURS OF INVESTIGATING, EXPERIMENTING AND SCIENCE FUN IN THE HOLIDAYS Each school holiday we bring a different theme to our venues in Bishop’s Stortford, Hertford, St Albans, Saffron Walden, Loughton and Cambridge. Our next camps are in the Summer holidays and booking is open now. This Summer we have three different events to choose from. Try out a whole orchestra of experiments in Super Sounds, investigate the rock cycle using chocolate at Geology Rocks and use pulleys, levers and more to develop your own designs at Magnificent Machines.
