|Fill the jar about half full with vinegar. Add the raisins. Add baking soda a little at a time until you observe the raisins in motion.
|Adding the baking soda slowly in small amounts will avoid a large mess.Make sure the students do not eat the raisins after the experiment
|If raisons are not effective try small pieces of spaghetti. Add some food coloring to the vinegar so that the spaghetti is easier to see.
|This is a good example to show children how two substances can create a reaction. The baking soda causes the vinegar to release carbon dioxide gas. The gas bubbles then stick to the raisins and cause them to bounce up and down in the liquid.
