You only need a few items for this activity, and the kids will beg to do it again & again! Are you ready for "take-off"?
How to Make Ghost Rockets
Materials
- Film canisters
- Corn starch
- Water
- Black marker
- Alka seltzer
- Stir stick
Method
- Begin by drawing ghost faces on clear film canisters like these.
- We used a permanent marker to avoid smears during play.
- Once the marker is dry add 1-3 tablespoons of corn starch to each film canister.
- Then, fill the canisters roughly 1/3 of the way with warm water and stir until combined.
Then it is time to PLAY!
Playing with Flying Ghost Rockets
- You will want to set off one ghost rocket at a time.
- Take a piece of Alka seltzer and break it into 3-4 pieces.
- Then, quickly drop the pieces in the canister, put the lid on, flip the rocket over, set it down, and stand back!
- The ghost rocket will go flying high into the air!
These ghosts really fly, too! Just look at that force of science propelling them!
So FUN! Rosie and Jewel loved making the ghosts fly and set off rocket after rocket!
Extend the Fun
Further explore science by adding varying amounts of ingredients.
- What happens with more or less Alka seltzer?
- What about more or less corn starch?
We had lots of fun experimenting, and I was surprised to discover that some of the ghosts flew the highest when less ingredients were used.
