Puddle GlumScience brain teasers require understanding of the physical or biological world and the laws that govern it.
Saku was feeling hungry one summer's day, so she decided to make herself a strawberry jam sandwich.
She spread the jam on the bread and when she had finished making her sandwich she went to pick up the jar of jam, only to find that it was now sitting in a puddle where previously there had not been one.
Where did the puddle come from??
HintIt was a puddle of pure water.
AnswerThe water had condensed on the jar from water vapour in the air, because she had been keeping the jar of jam in the refrigerator. The water then ran down the outside of the jar, pooling on the bench.
