I remember doing two science fair projects in middle school. For the first one, I tested whether the viscosity of a liquid would affect its boiling point. Turns out, the thicker the liquid, the higher its boiling point. Shocking, right?

The second year, I tested whether the temperature of various balls would affect how high they bounced. I learned that balls bounce much higher when they've been heated up. I also learned that a soccer ball will explode if you leave it in your oven too long.

Tell me your science fair stories. What'd you do for yours? Did your parents just do it all for you?

Also, *SHAMELESS SELF-PROMOTION ALERT* you should check out my conveniently science fair-related submission if you're so inclined.

I've only done the one where you prove a pocket of air can be found underwater. Super boring :/

Wait, what? Underwater pockets of air? Are we talking about bubbles?

Pretty much. just flipped a cup upside down and put it under water.

Ahaha. Sounds like quite the experiment. Gold star!

I made a complex polymer which could be manipulated and molded into a plastic or rubber material for manufacturing purposes - and it was all made out of corn

It did pretty good, made it to regionals

whooaaa.
That reminded me of this thing I did in Kindergarten, where we mixed something from a cleaning liquid and it made this material that was hard when you held and moved it, but turned gooey once you left it alone. I wish I remembered how to make it.

oobleck.

the one with cleaning product is slime made with borax. heavily toxic though. I'm surprised they even let us make that shit with kids anymore (I don't, but the enrichment teacher does it with 3rd graders).

In grade 7 I did an experiment to see if coloured light affected the growth of plants. I made lightboxes with coloured cellophane: clear, blue, green, yellow and red, and put the plants inside and measured them every day.

I don't remember the results, but after the experiment, my mom planted all the plants in one pot and I still have them 13 years later. They flower all the time.

Oh man, oobleck. I remember that stuff. If you have a big enough pool of it, you can actually run across the surface without falling in. Doing this is one of my life goals.

a giant pool of oobleck sounds amazing. I want to do it. This year I filled my classroom with 400+ balloons. Next year? oobleck. haha. that would be so rad/terrible.

In grade 8 we had to make a car powered by a mousetrap, and ours was awesome. we used records for the wheels and my partner Sheena's dad did the whole thing for us while we watched Hamsterdance on the computer. Oh, 1998.

I never did this kind of stuff, didn't exist where and when I went to school. But in (the equivalent of) high school, I was so nerdish about chemistry I stole chemicals from school and experimented in the home basement. I never consciously tried dangerous stuff like explosions, but I was too excited to be careful and got lucky a few times.
The awful smells sometimes made my mother check on me.

and in grade 9 we had to find a way to launch ping pong balls into a bucket 2 meters away using baking soda and vinegar.

We used really skinny pill containers that could be stopped with a cork, and we hollowed out the cork and filled it with baking soda, attatched the ping pong ball to the cork, and we put the vinegar in the container. When we put the cork in, the baking soda fell into the vinegar and the gas pushed the cork off and sent the ball flying into the bucket.

we figured this out without sheena's dad, and it worked REALLY well at home, and then at the science olympics (we did not have fairs) we spilled our vinegar all over the floor and it was terrible.

I won honorable mention in junior high for a sowbug habitat selection experiment. I made a wooden box with 4 chambers: dark & warm, dark & cold, light & warm, light & cold. Heat was produced by pocket hand-warmers, cold by freezer packs, and light level by an opaque or clear plastic lid.
Then I caught a bunch of sowbugs and put them in the middle, and recorded where they spent most of their time. They preferred dark & warm, which supported my hypothesis.

oh and each chamber was connected to other chambers by little doors in the dividers. If only I'd have had replicates! Coulda been published! Nobel for sure!

Whoa, that's actually a pretty cool project, Sam. I don't think we were allowed to use animals in ours.

I hereby request more science fair stories.

For example, did you know that you can make a battery out of a potato? TRUE STORY.
