Engineer It!

Today we went to this place called Sci-Tech, and it's present exibit was called Engineer It! and it was so cool. In one corner there were sailboats, paddleboats, and motorboats that you could build and sail on a little water table. That may have been my favorite part - I LOVE boats! Two adults helped a girl named Kariss, a boy and I make a caternary arch. It went up really high with foot-tall blocks numbered from 1 to 10 on either side, with a wedge-shaped 11 at the very top. Kariss, Cornflower (my 4yo sister), Mariel (7yo sis) and I had water in film canisters. You put a fourth of an Alka-Seltzer tablet in, closed it, shook it up, turned it upside-down and stepped back quickly. At any minute the bottom of the film canister (now facing up) would blow off - BANG! - and hit the roof (if you'd shook it enough) and leave the tablet fizzling out on top of the lid. Then, you could make a paper airplane and throw it at a triangle-shaped hole in a big pillar. If you hit, the airplane would fall through the hollow pillar and appear in a square hole in the bottom. There were some big legos in a bin, and a soccer ball glued to a lego to simulate a water tower. Once you had built a water tower with the ball and legos you could press a button and the black surface it was on would shake and shake to resemble an earthquake. Mine fell over as soon as I pressed the button. I did better with another girl on the earthquake platform. You used straps to hold the pillars and platforms together. She built a tall tower, and then she and I cross-braced it with straps on all 4 sides. It would not fall over, no matter how many times she pressed the button. Then she moved one of the bottom pilars. It all fell down. Kariss and I operated a pretend crane. She had the wheel to move the hook up and I moved it to the loading station and back. A group of little kids was there too. Some had dump trucks that took blocks with rope loops on them to a conveyor belt. Others made the conveyor belt move and hooked blocks on, as Kariss hauled them up by turning the wheel and I moved it to the dump truck. Teamwork rules! You could build paper bridges and block bridges and arrange gears and pulleys and build computer bridges. There was a small room called the wind tunnel, and you put these big foam wings on, pressed a button, and air would blow against your wings and you could expiriment with them in different directions. When it stopped, your turn was over. Then two ladies summoned everyone, kids and adults, to the place everyone had made parachutes at. One had a bottle of 7-up, the other a package of Mentos. They asked everyone to say what they thought would happen when they poured the Mentos into the 7-up. I predicted it would fizz all over the place. Then they put on saftey glasses and hard hats. They poured the Mentos in quickly and stood back. It fizzed almost up to the ceiling! Kariss was sitting next to me when one of the Mentos flew up and landed in her lap! She ate it, and said it didn't tast like 7-up at all. Whatever it tased like, my hypothesis was correct! That was the end. Please share your fun field trip stories!
