Have a blast-off! Pop a cork!
- tomato juice
- lime juice
- grapefruit juice
- 3 large clear glasses
- baking soda
- 3 1/2 liter water bottles
- corks that tightly fit the opening of the water bottles
- safety goggles
- paper and pencil
- Check with a grown-up before you begin.
- If you've ever made a Lemon Juice Rocket, you'll remember that lemon juice and baking soda combine to form bubbles of carbon dioxide gas. But it's not just lemon juice that can make bubbles and pop a cork. Test out three different acidic juices to find out which can shoot a cork rocket the farthest. The ZOOMers tested lime juice, grapefruit juice and tomato juice.
- The ZOOMers charted their results. To make your own chart, write the liquids you test in rows on the left side of your page and write the results you want to track in columns at the top of your page. The ZOOMers recorded Height of the Bubbles, Reaction Time in Cup, Height of Rockets and Reaction Time of Rockets.
- Predict which liquid will be fastest and slowest. Predict which will go highest and lowest. Write your predictions on your chart so that you can compare them later to your results.
- To start the activity, put one teaspoon of baking soda in each of three clear glasses.
- Add one cup of each liquid you are testing to each of the glasses.
- Observe and chart the reactions of each of your liquids to the baking soda. Which liquid bubbled the highest? Which reacted the slowest? Write your results on your chart and compare them to your predictions.
- Now, test these liquids as rocket fuel. Make sure you do this part outside, because these rockets make a mess when they blast off.
- Based on your results from testing the liquids in glasses, make predictions about how well each rocket will perform. How high will it go? How quickly will it blast off?
- Write your predictions on your chart to compare to your results later.
- To build your rockets, pour one cup of each liquid you are testing into each of your water bottles.
- Make three fuel cells out of one teaspoon of baking soda wrapped in a square of toilet paper.
- Test one rocket at a time. Just drop the packet of baking soda into the bottle, put the cork in the top of the bottle and wait.
- Time how long it takes to fizz up and launch the rocket. Compare how high the rockets fly.
- Once you have launched each of your rockets, record your results on your chart.
Compare your results to your predictions. Were you spot on or way off? Why do you think the liquids reacted they way they did? Make sure you send your results to ZOOM!

My results is when I put the lemon juice and baking soda in to the bottle it created a chemical reaction pushed the cork in out of the bottle.

The vinegar and the lemon juice reacted in about average 2 1/2 seconds. When the orange juice and coke just fizzed, so it worked.

what happend is it needed some baking soda and lime or lemon to do it. so frist we put a bottle in the middle of the table next we put the lemon jucies in side the bottle. then we put the baking soda inside and hrey and put the cork inside the bottle. then you waent for five min and its started to blow up and the cork flys in the air.

When I did it the lime was the only one that bubbled in the bottle and cup. This was a fun experiment to do. I want to do it again. I predicted that the lime was the only one that will shoot and I was right. This is a good experiment to do for a progect, science progect ect, and at home you will have alot of fun doing this progect.
