In high-school science was always one of my favorite subjects. I was one of those students always pestering the teacher with questions about why stuff happens. As I was cleaning out some of my stuff last week, I found a collection of my science experiments for kids. As they don't really help me anymore, I have decided to post a couple here.
So here are some of my science experiments for kids
Baking Soda and Vinegar Rocket
Equipment -
- Baking Soda
- Vinegar
- A one liter Bottle
Method -
- Fill the bottle with about an inch of vinegar
- Fill a small bag with baking soda and loosely seal it
- Put the bag in the bottle

- Warm water
- Red food coloring
- Detergent
- 2 tablespoons baking soda

- Stand the bottle in the dish and mould the mixture into a volcano shape. Do NOT cover the hole or allow anything inside it

- Using the paintbrush, write a message on paper, using the mixture
- Allow time to dry
- Hold the paper near something hot (like a light bulb) to make the ink turn visible
