Saturday Morning Science Experiment: The Gummi Bear Gets It

Grab your favorite sugary cereal and pull up a seat. It's time for Saturday Morning Science Experiment! This week, we're finding out what happens to a gummi bear (i.e., sucrose) when it's dropped into molten potassium chlorate.

Got a video you want to see on Saturday Morning Science Experiment? Drop me an email, I'm taking suggestions.

  1. That was one of my dad’s, high school chemistry teacher, favorite experiments to perform for his chemistry classes.
    Very cool!

  2. Something fun I actually did with gummi bears as a kid: Drop one in a big glass of water. Leave it in there for a day or so. It will grow and grow until it fills the whole glass!

  3. LOL that was hilarious! I expected it would melt and turn weird colours or something. What a reaction! :D

    1. Sekino, if your “What a reaction” was a nod to Don Showalter in the World of Chemistry videos, you win my person of the week award. You don’t really get anything for the award, but I will think highly of you until distracted by something shiny…

  4. You can try that science mumbo jumbo with the other peons, but I know that reaction is a result of Satan being released from his natural sucrosey habitat.

  5. awwwwww, poor gummi bear! Where are animal rights activists when you need them? Isn’t this a veiled suggestion toward animal cruelty? (Dear Lord, please know I’m kidding; never know with these teabagging wackos on the loose packing heat & dreaming of doing Beck & Limbaugh in a threesome)

  6. As for suggestion, do they need to be Saturday Morning Chemistry Experiments, or can they be Saturday Morning Physics Experiments?

  7. Not to supersede whatever videos may appear in future episodes of SMSE, but if you like science, physics and chemistry I suggest you check out the following three YouTube channels that come from the University of Nottingham:

    Absolutely my favorite YouTube channels out there which are criminally underwatched. PeriodicVideos is exactly that, each video about a different element on the Periodic Table and experiments that explain each one. SixtySymbols is all about explaining hard-to-grasp physics and astronomy terms and theories. NottinghamScience is a behind-the-scenes look at Nottingham University’s science departments.

  8. I’m thinking any saturday morning biology experiments that would pass the yawn test would be unethical, illegal, or both. I could be wrong, tho…

    1. Which brings up the question of whether it’s ethical to use gummi bears in such experiments. Stop the sucrose slaughter!

  9. Gummi Bears,
    Combusting here and there and everywhere,
    Molten potassium chlorate that’s beyond compare,
    We are the Gummi Bears!

  10. Looks like there a lot of energy release in that reaction there. We should make a gummi-bear powered car.

  11. My 10-year-old started with COOOOOOL! and ended up with “they’re murdering gummy bears”….which transitioned into — whoa, look at the chunks flying out of the test tube!

    I’m so proud of my little geek.

    Bring on more videos!

  12. I never knew those little bears could scream so loud… why don’t they do that when being eaten?

  13. Hmmm. . .isn’t KCl what most states use for lethal injections? Course anyone who could get potassium chlorate would probably know that already.

  14. Foolish loosely science-based Sky show Brainiac had an excellent little section in this vein, called ‘Will it Fizz, or will it Bang?’

  15. I wonder how a giant gummi bear that’d been soaking in water for a day would taste.

    I think that’s an experiment I’ll be skipping. Although I dare someone to do it and post video. :P

  16. Soak gummy bears in vodka. For a week (it takes a whole week, and you must cover & refrigerate & stir on occasion).
    They double in size. And wonderfulness.

  17. @Legless_Marine:

    You can’t even mention potassium chlorate on a blog without getting on a watch list.

  18. Holy ursine jell-o grenade, Batman!

    Not sure if I was seeing that correctly, but… was that reaction actually giving off *light*?? Way, cool!!
