Summer is here. I'm upstairs at our place and it has to be at least 30 degrees... what I wouldn't give for a nice dip in lake Erie right now! Thinking back to all of my summers spent at the lake, I remember making a fascinating discovery: While you're under water, if you take your hands and form a canopy over your eyes like you do when it's really bright outside, then carefully blow air upwards, the air forms a bubble over your eyes, held in place by your hands, that allows you to see under water as if you had goggles on. I'm sure this has been discovered many many times, but I was thoroughly pleased with myself!
