Anyone have a few of these lying around? I'll be honest the results were pretty weak, but my kids loved this science activity - They want more candy science tomorrow...So with a SweetTart, I found two different "experiments". Both produced better results with a crushed candy (which may have been the part my boys liked the most, crushing - what's not to love) - So this is before - an intact candy and chipping fingernail polish in a lovely blood shade for Halloween.
here under "candy erosion" Don't even bother with the hair dryer option - these candies are way too tough, no erosion = boring. What we did is pour vinegar over the candy and watch, partially crushed (edges) erode. It was very mild, but worked and maybe my kids understand something about erosion now (That it takes forever).
here. She has really cool ideas for tests and she explains them simply and scientifically. Again this worked faster with a crushed candy.
First she explains "Sour taste is the body's way of identifying acid, so if your candy tastes sour, it contains acid. "
What to do:
- Dissolve the candy in a half-cup of water.
- Sprinkle a spoonful of baking soda into water.
- Watch for bubbles. If it bubbles, the candy is acidic.
