So i have a little sister from Big Brothers Big Sisters. I hang out with her once a week. This week, we did some pretty cool science experiments.
First one we built a volcano! She was pretty excited about that one!
You can use baking soda and vinegar to make it explode.
After that we did a color wheel in Milk. It really didn't do much but she enjoy putting food coloring in the Milk.
After that, we tried to put an egg in a milk bottle. You have to soak the egg in Vinegar for 2 days, which i only soaked it in for 1 day. Then you boil the milk bottle, and put the egg on top of it and as the milk bottle cools the egg is supposed to fall in. Well it didn't work but we tried! haha
Then, we tried this thing with cornstarch and water! It was so cool you take 1 cup of cornstarch and 1/2 cup of water. So if you keep moving this it stays a solid but if you stop moving it, it becomes a liquid! It's honestly fun, kind of messy but easy to clean!
Then after that for the finale we did the coke bottle and mento's trick. If you put 6 - 8 mento's in a coke bottle it reacts and spits up. Well Jeff put the mento's in then Shake it, and threw it!
It was cool to watch.
In the little bottles you put 3 mentos in.
we had a lot of fun!
