Amy Torf from Noggin Builders talk about some fun science activities for kids.
16 ounce plastic soda bottle, empty & clean
1/2 cup 20-volume (6% solution) hydrogen peroxide liquid
liquid dish washing soap
1 Tbsp of dry yeast
3 Tbsp of warm water
Hydrogen peroxide (H2O2) can irritate and burn the eyes and skin; do not allow direct
contact; in case of contact wash / flush with large amounts of water immediately
Note: this project is messy! Find a place to do it where you don’t mind an overflow!
- Put on safety glasses
- Pour hydrogen peroxide into the bottle with funnel
- Add food coloring into the bottle
- Add 1-2 squirts of liquid dish soap into the bottle; swish the bottle to mix it slightly
- In a separate mixing cup, combine the warm water and the yeast together; mix
- Pour the yeast water mixture into the bottle with the funnel; quickly remove the
funnel and watch!
paper cup, bucket, or other container
plastic (bag, shower liner, etc)
rubberband, tape or bungee cord
- Cut a hole in the closed end of your cup / bucket
- Stretch plastic across the open end of the cup / bucket and secure with tape, rubber
band or bungee cord
- Tap the plastic to create a burst of air from the cannon
Pom Pom Blaster
- Poke a small hole in the closed end of your cup; test to make sure it is a snug fit with
the pom pom
- Tape the cup securely around the outside of the open end of the cup
- To use – gently blow into the small hole, inflating the bag. Place the pom pom snugly
in the hole. Aim and quickly squeeze the bag to send the pom pom flying.
