Nothing will make me not love peeps but I am excited to do these experiments. What a great idea.

haha, I feel a bit bad torturing these poor Peeps but we have had a lot of fun with it! It’s all in the name of science, discovery & explorations!

The “Peep Experiments” are great. I’m going to try them out with first my sons and then the classroom.

have fun with it & be sure to share what you do!

It might be interesting to compare how something else dissolves in each of those same liquids now. Maybe baby carrots or grapes or something. (Can you tell my son’s first science fair is coming up?)

Carrots and grapes don’t dissolve.

What about different flavor of peeps

That is insane! Thanks for sharing, really interesting to see this one!

It is Funny that you are always told (or tell your kids) that a Peep is all sugar-
However Sugar dissolved in water- the Peep- Not so much!

really funny anonymous

I am planning on a Waster Unit next week in my Preschool classroom and this sounds like an interesting experiment. Thanks for sharing!!

Wow, what a FANTASTIC experiment. I want to try this with my daughter.

I have been loving your experiments with Peps and Chicks!

Well that shows me that the vinegar is def a fat burner!

I think peeps are more sugar than fat.

I don’t think we’d ever be able to get the experiment done. my boys would eat the peeps! Looks like so much fun, though, so I might try!

I started this experiment in my 3rd grade classroom this morning. Instead of apple juice I chose liquid starch and vegetable oil. I’m excited to see the results as well as my students.

hope you had some grossly interesting results!

I finally had to throw them out yesterday afternoon after the students left. The peep in water molded, the peep in coke and vinegar became slimy, but still resembled the original peep shape. Yikes! Oh, and no change in the peeps that sat in liquid starch or vegetable oil. Now, I can honestly tell my mother PEEPS are not just pure sugar. Thank goodness I never liked them!

just wanted to share that I did this experiment at school with my kindergarten! they loved it! we used water, coke, orange juice, vinegar, vegetable oil, and kitchen cleaner similiar to 409 with bleach! i used the bunny peeps so they were not as thick. after 4 days, the vinegar had completely dissolved the peep! the vegetable oil showed no changes at all! the sugar was still on it even and it was just hard like a stale peep. coke was gross! lol! thanks so much for sharing! it was a great inquiry lesson the week before spring break to keep their attention.

So glad you all had fun with it! Next year I will definitely go for the dissolving bunnies to be able to see changes faster!

Wasn’t it gross and cool all at the same time? That’s what my girls loved about it!

Thanks for sharing – the vegetable oil is a interesting result. I will have to try that next year – sounds pretty yucky which is fabulous! 🙂

Did this w/my 1st grade son & his friend. They chose lemon juice, vinegar and ginger ale. The vinegar changed in texture/size the most, lemon juice was 2nd, ginger ale the least.

Much more interesting would be to see if the Peep dissolved in hydrochloric (stomach) acid. If that doesn’t work, then I’d say, “No more Peeps!”

I think you need to change laundry detergent! We are doing this now, using the same basic liquids. our Vinegar peep is foaming, but still intact on day 4, but our laundry detergent peep (Kirkland/Costco Environmentally Friendly [or whatever] brand) didn’t even last a full 24 hours! The eyes & nose are still around on day 4 though; makes you wonder what THOSE are made of! We’ll try it again in about a week for my 1st grader’s science fair, and switch out some of the solvents. 🙂

those eyes were resilient! Thanks for sharing. My detergent is very mild because my youngest has eczema so it’s not harsh – maybe that’s why we got the result we did?

I did a sort of similar experiment which started one cold day when we noticed (on the way to school) that the road had been gritted with rock salt. I explained why and when we got home we put three small tubs of water, one plain, one with salt and one with sugar, in the freezer and checked them every hour.

I remember watching a “Chopped” episode where the contestants had to make a meal, and peeps were one of the ingredients the contestants had to use. If I remember correctly peeps were dissolved into a sauce on the stove using ingredients such as a white cooking wine.

Yuck! I knew that there was a reason that I did not eat Peeps. 🙂

gross – I have never been a fan of peeps!! I do know they expand in the microwave

Peeps are just marshmallows covered on sugar, and so if you put it on the stove eith a little butter just like rice crispues itll melt

Don’t care what happens to the Peeps- I love them!

I believe this was a good experiment to show why we need more vinegar in our diets. It helps to break down the yucky in our intestines.

What does that actually teach kids? Are we trying to show kids about how chemicals can change states of matter? I do not see what the learning objective is here.

you can talk about how chemicals (the solvents) change states of matter (the peeps). To be honest, we did it for fun to freely experiment so I didn’t focus too much on the explanations as my girls were 4 & 5 years old at the time.

In our state, it is actually part of the standards for young kids (through second grade) to learn the scientific method. That means learning how to set up an experiement, learning controls and variables, make a prediction, observe and compare the prediction with the outcome. Plus, at such a young age, it is important to get them excited about learning. In this case, the experiment was not as important as them learning how to experiement. Everything doesn’t have to be so serious. 😀

Going to try this with my 5th grade science classes. One suggestion the students made was to use hot sauce! We are excited to try the experiment.

I did this today with my high school seniors. and we will only have 24 hours but we saw immediate changes. We used orange juice, lemon juice, vinegar, coke, laundry detergent, amd water with baking soda. This is really fun and the kids are all guessing what will dissolve it!

Does anybody put their Peeps in hot chocolate?

Tried this at home with my 4 year old daughter. We used lemon juice instead of apple juice and didn’t see much of a difference. The biggest difference was the laundry detergent. We used Tide and there was hardly anything left! It shrunk it down to almost nothing.

that’s really cool I think I should have done that for my science fair project

Can you use marshmallow in place of chicks?

I think this would be great for a 1st grade science project, especially since Easter candy is out already!! Have you ever put one in the microwave?? VERY cool!!

Yes, that’s how I eat them every year.

I’m doing this at school for our Science Fair; however I’m having a very difficult time coming up with a hypothesis. Any help would be greatly appreciated.

How much liquid did you put in each cup?

You should teach them about the scientific reasoning of why this happens. The reason it’s vinegar is because it’s CH3COOH, and since it’s an acid it will dissociate into H+ ions. These H+ ions will work at breaking apart the benzene ring of glucose and creating new strong hydrogen bonds. Soda and apple juice are both acidic, but not as much as the weak acid vinegar; However apple juice is more acidic than soda due to the citric acid present. Then you have water, which is perfectly content not dealing with the massive glucose molecules, therefore not having it dissolve fast because the bonds in H2O are stronger. Laundry detergent would work effectively also due to its basic nature, creating OH- ions that would work at taking off the H+ ions hanging off of sugar. The vinegar won because it was a stronger in acidity than the laundry detergent was in basicity. There is your somewhat watered down chemistry lesson.
