Ingredients
Scale
Materials
- 6 empty 35 mm film canisters with tight-fitting lids (or mini condiment cups with snap lids)
- Safety goggles
- Outdoor space for launching
Rocket Ingredients
- Vinegar (white or apple cider), about â…“ full per canister
- 1 box baking soda OR Alka-Seltzer tablets
- Optional: 2–3 drops of food coloring per launch
- Optional: pinch of fine glitter per launch
- Funnel or small spoon
- Small pieces of tissue (for holding baking soda packets)
Instructions
- Prepare and protect: Wear safety goggles to protect your eyes and set up your launch area outdoors for safety and ample space.
- Add vinegar: Fill each empty film canister about one-third full with white or apple cider vinegar.
- Enhance colors and sparkle: Add 2–3 drops of food coloring and a pinch of fine glitter to the vinegar in each canister to create colorful eruptions and glitter trails when launched.
- Create baking soda packets: If using baking soda, place 1 teaspoon into a small piece of tissue and twist it closed to form a time-delay packet that slows the reaction upon contact with vinegar.
- Load and seal rockets: Quickly drop the baking soda packet into the vinegar-filled canister or add half an Alka-Seltzer tablet if using, then snap the lid on tightly. Immediately flip the canister lid-side down onto the ground to contain the pressure.
- Launch and observe: Step back at least 6 feet for safety and watch as the pressure builds, causing the canister to pop open and launch into the air as a rocket.
- Repeat for more fun: Use fresh ingredients and clean canisters to enjoy multiple rounds of launching and experimentation.
Notes
- Always wear safety goggles to prevent injury from the popping canisters.
- Conduct the experiment outdoors to avoid mess and allow rockets to launch freely.
- Use caution when flipping and handling canisters under pressure.
- Adjust the amount of baking soda or Alka-Seltzer to change the strength and height of the launch.
- Adult supervision is recommended for children during the experiment.
