Want to visually explain how bleach works? This is as easy as it gets!
What you’ll need for this project:
- Two clear plastic cups
- Food coloring (red is great to use)
- Bleach
- Water
Directions:
- Fill one plastic cup three-quarters of the way with water
- Add several drops of food coloring to the water and mix it up until it is red/pink
- Fill the other plastic cup one-quarter of the way with bleach
- Slowly add the bleach to the water mixture
- Watch as the bleach expands the molecules of dye attached to the water molecules, thereby making the water look clear again
WARNING: Do not under any circumstances drink the bleached water!
2: Buoyancy “Magic”
For this project, you’ll need only a ketchup packet and a one- or two-liter plastic bottle filled about three-quarters of the way to the top with water. Pop the ketchup packet into the bottle, and then squeeze the bottle to see if you can make the packet move up or down. Try different packets, such as those of mustard or soy sauce. Do they move the same way as the ketchup packet did?
3. Rain, Rain, Don’t Go Away!
Make it rain inside your house.
You’ll need:
- A plate
- A glass mason jar
- Ice cubes (about one or two cups)
- Very hot water
Place the hot water into the glass jar, about a third of the way up. Put the plate on top of the jar. Place all the ice cubes carefully on the plate. Watch the inside of the jar start to exhibit rain!
