Get sparking at Lates 6.30-9.30pm at the National Science & Media Museum in Bradford.

Sending out an SOS.... using some paper clips, some bits we found in old door-opening mechanisms, a 9v battery and some croc leads, we can now help you to broadcast an emergency distrss signal to an incredible range of nearly 2 metres! Just make sure that potential help is within that distance and you can rely on rescue, although the circuit is a bit fiddly...

Feel 1000 watts of bass power though your fingers, make laser-blaster sounds with a slinky, and discover amazing sounds hidden in everyday objects with Noisy Toys and their sound experiments, demonstrations and short workshop activities. Find us at the Beacon, central Bristol.

Join us to explore the very first discoveries and uses of radio waves with a very simple feedback circuit. It makes a Buzz as it switches itself on and off very fast but we find that it is also transmitting radio waves. We might also make a robot chicken circuit along the way and maybe learn a bit of Morse code too.

Recommended for ages 10+ or with adult supervision
