Todays home education included a good deal of garden play, potting and burning leaves with a magnifying glass, because it was so sunny.
However, we have also made an animation and built the final circuit from our Maplins Electronics kit, one which uses a cool component called a Quantum Tunnelling Composite pill.
The circuit has a QTC pill between two all metal spoons, which are connected to +ve and -ve, with a motor wired in series also.
The harder the spoons press the pill, the faster the motor runs.
The QTC pill starts as a insulator but conducts better when squeezed. You can see it in the above picture as a small black object on top of the left spoon.
The booklet claims that it 'teleports' electrons across tiny gaps. This circuit is a form of analogue resistor, rather than a digital switch. There isn't a whole heap of information about QTC, so if you have a good link, please share it!

We will probably do another version of this animation to make the electrons a bit more teleporty.
