Question: What are some really cool/interesting Science Experiments that I can do at home?

I’ve tried the egg in the bottle, using matches experiment, the water into a glass using matches, and some others; all of which were great!

Any other cool experiments would be fun to try, Thanks!

Answer: I would suggest the following experiments:

1) Growing mold on a slice of old bread.
All you need for this is a slice of old bread, a plastic bag that can be sealed and a small amount of water.
Put the bread and a few teaspoons of water into a plastic bag and seal it. Place the bag in a dry/warm area and leave it there for several days to a week. Every day, check the bag. For the first few days, you can add a teaspoon of water (but don’t oversaturate it) if the bread seems dry. After a couple of days, you should start seeing mold growing on the bread. It may take several forms and different colors. (Once you see the mold growing, do not keep adding water.)

2) Demonstration of capillary action
You will need a celery stalk (or carnation), a tall glass, water, and food coloring.
Take either a celery stalk or a carnation (white flower is preferred). Place the plant material into a tall glass with colored water. Place this in the fridge. Check it every day. Within a few days, you should start to see colored lines (from the colored water) in the celery stalk or carnation. If you let the experiment continue for a while, the top of the celery stalk or carnation flowers should show some color.

Worlds coolest science experiment, to do at home!!!!
