BTW, terraria aren’t meant to be pressurized beyond the weight of the water, so obviously, if you do this, don’t crank it too high and WEAR SAFETY GOGGLES. ---

Thanks for the link, ENugent. I guess. :eek: Even though it’s not quite the same region we were discussing. ---

Get 2%,1%, whole, and skim milk, put it in little cups, then blindfold people and see if they can tell the difference. ---

Ford explorer vs honda civic etc… I remember seeing on the Today Show a couple of years ago, the first place national high school science fair winner won a full scholarship to MIT. She built a blood CO meter. ---

One of my H.S. science fair projects was pretty interesting. You might give it a shot. Simplified explanation below: Everyone knows that plants grow toward light. Everyone knows that upside-down plants will eventually “right” themselves and grow rightside-up. What happens if you turn a plant upside-down and place a light source beneath it? I know the answer… 🙂 ---

I am definitely going to try it as soon as I get home! ---
