Dig the old pennies:
And the new pennies:
Well, maybe you can't really tell in the picture, but it was super-dramatic and also instantaneous. Awesome. Maybe this has something to do with why salt and vinegar potato chips taste so good, though further research needs to be done on this subject. Please send salt-and-vinegar potato chips.
The second experiment was much more like Actual Science, because it did not work at all. We put some baking powder in a packet of toilet paper in a glass and put some pieces of spaghetti in the packet. Supposedly, when you pour vinegar on this, the resulting carbon dioxide bubbles on the pasta shoot them up like rockets. Here's Ben adding the vinegar:
2 foamed out onto the table, so it wasn't a total loss.
*No, silly, we're not sacrificing taste for nutrition. (Remember, we're baco-vegetarians). This tastes BETTER than white pasta. This isn't that Healthy Harvest crap they have at the grocery store. It's imported from Italy (and it's still $2.50 a pound through our dry-goods co-op) and the best part is it still comes in packages of a pound. Remember when pasta came in pound packages?
Finally, we turned to physics, sort of, by making parachutes. Practically everyone has done this at some point, so you are probably familiar with the idea. We were supposed to use corks for the parachuters, but could only find one, so we ended up with one cork ("Steven") and one cardboard cutout person ("Allison"), who flew really well, especially after we cut off everything below her neck to reduce the weight. Steven's parachute was a little more symmetrical so he had better aerodynamics and often got carried impressively far laterally by the wind, but overall, Allison fell more delightfully slowly. Here they are being released from the tree house:
