Feed the yeast!
- 3 packages of yeast
- warm water
- 3 clear, 16 ounce, plastic water or soda bottles
- funnel
- 3 balloons
- rubber bands
- various sugary liquids, like cola, apple or orange juice, and corn syrup
- Check with a grown-up before you begin.
- Cara of Maryland sent us the idea to do an experiment to see which liquids yeast like the best. When Matt and Estuardo did this on the show, their hypothesis was that the more sugar a liquid has, the more the yeast will eat it, and the more carbon dioxide it will produce. Here's how you can test it out.
- Add 1 package of yeast to each bottle.
- Fill each bottle 1/4 full with warm water.
- Fill the first bottle half way full with one of your sugary liquids, like cola.
- Fill the second and third bottles with different sugary liquids. Make sure you add the same amount of liquid to each bottle.
- Put a balloon over the opening of each bottle. The balloon that inflates the most will show which liquid produces the most carbon dioxide.
Which of your liquids do you think will produce the most carbon dioxide? Make a prediction, and then test it out. Be sure to send your discoveries to ZOOM!

Instead of changing the type of liquide I used water and different amounts of sugar. I used 1 teaspoon of sugar, two teaspoons of water and 1 teaspoon of Sweet n low. The one teaspoon of Sweet n low produced the most carbon dioxcide. Then the 1 teaspoon of sugar. Following is the 2 teaspoons of sugar.

the cola soda won!

I used root beer, lemonade, syrup, orange juice. The lemonade produced the most carbon dioxide. Yeasts grow best in a neutral or slightly acidic pH environment, thus the reason why lemonade produced more.

i did the project diff. I used 1 pac. of yeast, 1warm cup of water, 2tables. of sugar, balloon bottle. what happen was foam got in balloon where did the yeast go

well we used diff. materials, but it was cool.
Alexis, age 11 of Fort Lauderdale, FL wrote:
I used grape soda, apple and orange juice. The apple juice blew up the most.

It worked, but the balloon popped, can you tell me why? Ehh. The yeast got everywhere, yuck! I had to clean it alll upp!

This experiment is so cool I am going to use it for my science fair project when I showed it to my science teacher he loved it.

Yeah, this project was really fun I really enjoy it, and yeah the soda inflated the balloon the most. Thank you this project really help me at my science fair project!

Iused Coke, corn syrup, and grage juice. The Coke turned out to be the biggest ball.

Man, this experiment was really fun! When I did it the soda inflated the balloon the most. I used this for my science project this past year THANX ZOOMsci!!!

I used Coke, Apple juice and Tum-E-Yummies greentastic apple. The biggest was Coke, 2nd was apple juice and 3rd was the Tum-E-Yummies. I used it for my science project and took pictures every 15 minutes. It was so cool!

the cola blew the ballon up the most because of all the asit. that makes corben dioxid which fills the balloon.

We are going to use OJ Coke and maple syrup. Will it work? We'll see soon!

i did this for my science project/fair in fifth grade. Though I didn't win the fair, I scored a great grade with the judges, and it was popular with the little kids.
Cynthia, age 12 of New York City, NY wrote:
coke had the biggest balloon. zoom is the best! it helped me with my science project.
Takalyn, age 13 of Harvey wrote:
i had got a lot of different results at first but when I got done oj had won which had the balloons bigger

it blew carbon dioxide in the balloon it was kool!

I thought the cola was going to win. But the OJ won.

i used corn syrup, orange juice, and apple juice the biggest was corn syrup the 2nd biggest was apple juice and the smallest was orange juice.

when I did it cola was the one with the most codon dioxide.

it was cool. iliked it it blew up I liked it
Mohogany, age 10 of Missouri, TX wrote:
when me and my sister did it we discovered the cola gave off the most carbon dioxide. while the others produce less carbon dioxide, it was great for my science project thanks ZOOM!!!

We did this experiment for our school science fair. We tested 5 liquids (vitamin water, orange juice, coke, kool aid, and corn syrup). We had a strange result. The coke had the most sugar but not the biggest balloon. We think it was because the yeast had TOO MUCH sugar to eat. We also noticed that the coke bubbles overflowed and went into the balloon. Next time, we might want to use a taller bottle and see what happens.

The cola was in 1st place 2nd was a tie between orange and apple juice.

Cola gave more

It was really cool the balloons popped up and some were bigger than others! I did it for my science project last year!
