It’s going off in a big way. Doing exactly what it says on the (exploding syrup) tin, come and be blasted with colourful explosions and chemical reactions. Witness everything from rapid colour changes to clock reactions, gun cotton, sticky tape bombs, indoor fireworks, hydrogen rockets, water fires and phosphorus globes.

Part of Manchester Science Festival, 18–28 October. Visit manchestersciencefestival.com for more info.
