You have most likely done both of these expirements before, but they're always fun to do again lol. Here's the first one. (I took parts of it from HERE, because I'm to lazy to type it all out myself haha.)
Materials:
Balloons
Small funnel or a small piece of paper rolled up in a funnel shape
Baking soda
Vinegar
Ice Cubes
A big liter jug that used to have sodaa or something in it. Make sure that it's all clean!
Saucepan
Water
Red Cabbage (It's purple colored.)
Directions:
Take a couple of leaves off of the cabbage and put them into the saucepan along with 2 cups of water. Turn on the burner, and leave it on until the water boils.
While the cabbage water is boiling, use the funnel to add 2 tablespoons of baking soda to each balloon.
Fill the bottle with 1/3 cup of vinegar
By now, the water should be boiling. Once it's boiling, turn the burner off and add some ice cubes to help cool off the water. Let it cool for about 30 seconds.
Then put 1/2 cup of the cabbage water and put it into the bottle. Make sure that none if the leaves get into the bottle!
Make sure to watch all of the color changes!
Without dropping in the baking soda, fit the balloon over the bottle opening
Hold up the balloon and let the baking soda fall into the vinegar
Watch as the baking soda mixes with the vinegar to make carbon dioxide gas and blow up the balloon
What's Going On?
The vinegar mixes with the baking soda to create a chemical reaction that produces carbon dioxide gas. The gas then blows up the balloon.
Ya, so it's pretty fun...you have to admit! Did you do it? Let us know, in a comment of course lol.
