    i put mi bottle in the frezer!

  2. You may need a larger mass of air to make the coin dance… try again? You’re getting a result, and it may not be the one you wanted, which the mark of a good science experiment. Your job as a scientist is to watch carefully and figure out what’s going on to make it act the way that it did, and then adjust what you’re doing to get the result you want. Keep trying!!

    We tried this with the water bottle and were not successful.

  4. How big is your bottle? Larger are better as they won’t warm up nearly as fast. I wonder if it would help to rinse it with water and then stick it int he freezer, or even surround it with a wet paper towel and then freeze it to help keep the bottle from thawing so quickly.

    We have tried this a few times and cannot get it to work. We’re using an empty water bottle like the one shown in your video. We put it in the freezer overnight uncovered and tried placing the quarter over the top when we pulled it out and we also tried placing it in the freezer with the quarter on top and pulling it out and nothing happens. The plastic bottle seems to warm up very quickly. Could that be the problem?
