Lessons don't always go as planned...

I don't mean to interrupt your Wordless Wednesday, but I have to share how our science lesson went this morning! (WW post is below) I thought I would be smooth this morning and do the old "universe is expanding" demonstration with a balloon and a marker. So I actually found a balloon and a marker and was all set to go. "This is what is happening to our universe," I say to my children, who are actually paying close attention. I proceed to blow up the balloon, and then it slips out of my hands and and goes shooting around the room and drops into a flacid, wet heap. Children look horrified. Then they giggle. Maybe they thought it would be fun?
