Dancing Pasta!
Fizzing Science Fun!
Welcome, Nerd!
It's another fun, easy-to-set-up Experi-Graphic from Pow!Science!
This fun, reactive experiment is a twist on the classic "Dancing Raisins" Experiment - our problem with Dancing Raisins is that the raisins so seldom actually dance. It's so frustrating! Interestingly, we've used pasta bits (as shown below) to far greater success, as well as "Craisins" which work extremely well! They must be less dense than raisins, though to be honest I've never measured.
Try "Dancing Pasta," and be sure to read below the Graphic for Extension Ideas.
Extensions
1. Use a clear soda (or just soda water) instead of the water, baking soda, vinegar called for here.
2. If you have access to Citric Acid Crystals, try a spoonful of those dissolved in a glass of water instead of the vinegar.
3. Try using "Craisins" instead of Pasta Bits. Try using Raisins, too! What works best?
4. Got a digital thermometer? Measure the temperature of the water before you dump in the vinegar and again shortly after. This is an endothermic reaction, meaning energy is absorbed, so you will see a drop in temperature!
