Entertain your little boffins with a weekend of free, hands-on events across Bradford, during the British Science Festival Fringe 2015.

This September, Bradford will be taken over by the The British Science Festival, and its kid-friendly counterpart, The British Science Festival Fringe 2015. And if you have young scientists in tow, then it’s the latter you’ll want to remember – as it promises a jam packed weekend of discovery, complete with explosions, rockets and mess.

Just a stone’s throw from Leeds, the festival crams 39 free activities into one action-packed weekend, covering all the big scientific bases, including wildlife, medicine and technology. For £5, you can even tuck into a science-themed lunch, making your mid-day meal a little bit more experimental.

With the National Media Museum’s CSI Family Weekend running both days, you can see how science defeats criminals. But that’s just the beginning. The City Park Science Market will have you up to your elbows making rockets and nano jelly on Saturday 12th September 2015, in between trips to Dr Ken’s Street Science Theatre. You can also watch scientific theories played out through dance or record wild animals on smartphone microscopes. It’s really up to you.

At the same time, Bradford College is inviting kids to dabble in TV special effects, with an inflatable obstacle course to wear them out ready for an early night. The British Science Festival Fringe 2015 is very hands-on, so you can mix your own sports energy drink, build a camera or see the world’s first printing pen, but when it comes to the Hollywood-esque chemical explosions, you’ll need to stand at eyebrow-protecting distance.

It doesn’t end there though, as Sunday 13th September 2015 sees the University of Bradford take over proceedings. Among the animal handling sessions, physics-themed comedy gigs and the chance to climb aboard a replica aeroplane, is a celebrity appearance from BBC One Show’s mad scientist, Dr Marty Jopson. His Zap, Crackle & Pop workshop will take you on a hair-raising tour through the history of electricity, with live demonstrations which may shock and surprise you.

The Family Weekend takes place between Saturday 12th September 2015 and Sunday 13th September 2015, while the British Science Festival Fringe itself takes place from Friday 11th September 2015 until Friday 18th September 2015.
