Have you ever ripped open a new toy on Christmas morning, ready to start having fun only to find your enthusiasm brutally dampened by not having the right sized batteries? This cunning hack just might save Christmas.
If you only have AAA batteries but the occasion calls for AA, a little bit of kitchen foil can ease your woes. Just scrunch a ball of tinfoil between the battery and the negative terminal.
