Here’s a project for half-term: magnetic LED throwies.

The Finished Article

First you’ll need an LED. You can buy them from any electronics supplier such as Maplin, Rapid or RS.

Lastly you’ll need a CR2032 battery. I bought mine from cheaperbatteries.co.uk.

Step 1: Place the battery in between the “prongs” of the LED.

Step 2: Attach the magnet to the battery and LED.

Step 3: Wrap the whole thing in electrician’s insulating tape, available from any DIY shop.

Step 4:

Props to Graffiti Research Labs for the original idea.
