fun things to do with batteries


2. if you are ever out of AAA batteries and you have everything else but them, take that square one that you use for fire alarms and CAREFULLY cut it open. inside will be 6 AAA batteries that are slightly smaller than the store kind but will work anyway.

3. if you take a D-cell and push it towards a AA of AAA, the smaller one will roll away, without the larger one touching it.
