For the following experiments you will need…
White vinegar, baking soda, a cooked chicken leg bone, 1-2 eggs, a recycled water bottle, balloons, measuring spoons and cups, a jar with a lid, a bowl, funnel, a spoon, a magnifying glass, a zip-top bag (sandwich sized), bathroom tissue and tape
Optional: Dish soap, food dye, a length of yarn, scissors, and a ruler

Experiment #1: A Chemical Reaction
In this simple experiment, you will add 1 teaspoon of baking soda and 2T of vinegar to a bowl and observe the results. You may have done this before, so to make it more interesting, add a few drops of your favorite colored food dye and a few drops of dish soap to the baking soda before adding the vinegar.
Experiment further to get the best reaction possible.

Experiment #2: Capture A Chemical Reaction
In this experiment, you are going to use a funnel to add 1 tablespoon of baking soda into a balloon and 1c of vinegar into a recycled water bottle. Carefully cover the top of the bottle with the open end of the balloon without releasing the baking soda into the bottle. When the balloon is in place, allow the the baking soda to fall into the vinegar and observe the results.Tips: Talk about what you think is going to happen before mixing the baking soda and vinegar together.
Measure how large the balloon gets with a length of yarn and a ruler.
Try the experiment with different vinegar and baking soda ratios, and fresh balloons of the same size, and compare the results.

Experiment #3: Bend A Bone
In this experiment you are going to start by testing the strength of a leg bone without snapping it. Next, put it in a jar, add enough vinegar to cover the bone and close the lid. Check the bone in 3 days and test its strength. Compare the results to the day you added it to the solution. In another 4 days check the bone again and test its strength again.
Put the bone back into the solution and check on it in a month.

Experiment #4: Rubber Egg
Put 1 raw egg in a jar and cover it with vinegar. Refrigerate the jar and check on it in 24 hours. Remove the egg carefully with a spoon and put it aside, then dump out the vinegar. Rinse the jar out, put the egg back in the jar carefully, cover it with vinegar, and refrigerate for another 24 hours. Remove the egg, rinse it off, and observe the final results with your hands and then with a magnifying glass.

Experiment #5: Cause An Explosion
You may want to do this experiment outside!Using two pieces of bathroom tissue put together, add 1T of baking soda to the middle, then fold it up to form a little packet. Use a piece of tape to keep it together.
Next add a 1/2c of vinegar to a sandwich sized bag.
Add the baking soda packet to the bag but hold it away from the vinegar while you zip the bag closed. When you are ready, drop the packet into the vinegar, and give the bag a shake before putting it down on the ground.
