Because what starts out small often grows large.
Because what happens by accident can also be done on purpose for a purpose.
Because ordinary materials can be used to make extraordinary things.
Because the five-year-old wants to do a science experiment.
1. Obtain, by any means necessary, a slice of bread:
2. Dribble three tablespoons (more or less) of water upon said slice of bread, apparently getting as much water on the newspaper that I'm trying to read as possible:
3. Put the wet bread in a Ziploc baggie (or a glass dish with a lid, if you're fussy about plastics), and hide it somewhere warm and dark. Visit it every now and then.
There, we've done a science experiment. NOW can I drink my coffee and finish the newspaper?
