HORSHAM College's science extravaganza returned with a bang on Wednesday.
The extravaganza, back after a two-year hiatus, featured biology, physics, chemistry and psychology experiments.
About 300 spectators were treated to smoke bombs, explosions and foaming concoctions in the college's science wing.
They also took control of a remote-control helicopter, donated by Horsham Fone Tek, during a physics experiment.
College science teacher Claire Breed said the event was a hit with families.
"It was a pretty good turn-out given that we haven't had it for two years," she said.
"A lot of primary school students came along and got involved they seemed pretty excited about science.
"There were plenty of smiles on people's faces and we have received some really good feedback."
Miss Breed said the science extravaganza centred on a food theme.
"In the food technology rooms, people were looking at different types of rocks sedimentary rocks were compared with rocky road," she said.
"We also had about 60 people involved in a mystery experiment where they had to use different fruit and metals to find which had the highest voltage."
Miss Breed said the college's students volunteered to run the evening's experiments.
"The best way to learn is to teach," she said.
