Organisers hope their forthcoming event won’t go with too big a bang, as thousands of adults and children have fun with chemicals and lasers.
More than 2,00 people are expected to descend on St John’s Academy for its fourth annual Science Fair on Saturday, March 16.
Run as part of National Science Week, the inaugural event in 2010 won an award from the British Science Association for the best school fair in the country.
The event offers families the chance to join in with experiments in the science labs, get their brains working in the maths puzzle zone and explore the latest gadgets in the technology zone.
Children are also encouraged to take part in a code breaking treasure hunt, Lego robotics, and rocket making with Cats House Observatory.
Better still, most of the events are free, while a small charge is made for some spectacular events, for which pre-booking is required.
Scientist ‘Dr Mark’ Biddiss will be bringing two shows to the show: The Cool Science and Maths Show, featuring exploding water, belching balloons, levitating balls, flying fish and vanishing loops is aimed at children aged four and upwards.
And his Tricks of the Mind Show show promises magnetic fingers, antigravity arms, handy force fields, and coloured ghosts.
Attendance at each show costs £4 for adults and £2.50 for children.
The Amazing Planetarium will be making a return visit to the event, with six shows over the day and a charge of £3.50 per person.
And the chance to engrave a glass using laser cutters takes place twice during the event and costs £4.
