Here are the rest of the experiments we did at the Mad Scientist party, in more detail:
6. Make your own slime: once again, Steve Spangler came through. Using the polymer and liquid solution provided, I amazed the kids with my ability to create slime. My job was to pour in the right amounts of solution, they had the fun part of shaking things up and seeing what happened. I got free containers from the local pharmacy to shake the mixtures in. And as you can see, some kids decided to add food coloring to their slime.
7. A water tornado in soda bottle: this trick was pretty cool–and mess free. Here goes, first I filled one bottle with water and left the other bottle empty. Then I connected them with a handy dandy tornado tube connector. If you tip the bottles over so the bottle with the water in on top, the water won’t fall down into the empty bottle because the air holds it in place. I asked the kids what they thought would happen and some guessed it right away. But once I “swirled” the water, it formed an awesome tornado. Then we added food coloring (because really, they wanted food coloring added to everything) and I let them each have a turn creating a tornado with the water. Ahhh, the wonder of physics.
8. In seconds you can have fake snow: super absorbent polymers and water combine to make instant snow. It was pretty amazing how fast the snow appeared after we added water to the white polymer powder. A must do.
9. Can you turn grape juice into purple soda pop? I started this experiment with two different glass pitchers that were different shapes, but held the same amount of liquid. I asked the kids to tell me which container held the most water and we talked about how containers can look different but really be similar. I measured 4 Tablespoons of citric acid and 2 Tablespoons of baking soda into the tall pitcher and then I added some grape juice (and you can see what happened). For the apple juice I added some dry ice to the pitcher. This didn’t make as fizzy of soda pop and I think the citric acid and baking soda worked better. I bought empty soda bottles to fill with the “soda pop” but you could just use cups instead. Notice the dry ice fog from the apple juice and the obvious chemical reaction from the grape juice. Either way, the kids liked both flavors.
10. Please tell me you’ve heard of the ‘ole diet coke and mentos fountain: it’s so easy. I bought a bunch of bottles of diet cola. And lots of rolls of minty Mentos. This isn’t necessary, but I bought this kit from EepyBird to make the experiment easier and more fun. Each team got a cool top and a pin with a string attached. They loaded their topper with Mentos, put the pin in place to prevent the Mentos from going into the Diet Coke before they were ready, twisted the cool topper onto the soda bottle, then they stepped back and pulled the string attached to the pin to release the Mentos and cause an awesome soda fountain. It’s not as hard as I’m explaining it here. We did this experiment last and I think they liked it best. And for obvious reasons, do it outside.
