Try out these kits, they're cracking!
Grab a few of your friends and using your mobiles, have a go at transmitting what you’re hearing to each other in different places.
Here’s the science bit: When we're standing in a noisy place, each of our ears hears a slightly different version of the sounds around us. This is because our ears aren't in quite the same place, and our head is in the way between them. Our brain uses these differences to figure out where individual sounds are coming from.Instructions below
1Firstly, check you have all the required ingredients listed in the box above.
Give your friend two of the phones, and keep the others.
2Using your two phones, call the other two.
3Your friend should answer both phones at the same time, and hold them to his/her ears.
4Take your phones and hold them to your ears, but back-to-front so the bits you usually speak into (the microphones) are facing away from your ears. Hold them so the microphones are the same level as your ears (higher than you'd normally hold a phone).
5Leave your friend in a quiet room and go somewhere noisy. Your friend should be able to hear not only what's happening around you, but where it is in relation to you.
