Fun With Baking Soda: Exploding Bags

Fun with baking soda - exploding bags

Boys love when things explode. So it is no wonder that for years boys have lived cherry bombs and baking soda bombs. When we were young they were available at the corner drugstore, the ice-cream man sold them, and we bought them up. Even us girls were not immune to the excitement of watching something blow up. It was mesmerizing, surprising, and exciting. It can also be educational if you get into why the bombs blow up in the first place. So this month why not have an impromptu science lesson outside in the warm sunshine with your boys. You just might find it to be a blast.

In the past we have discussed how baking soda and vinegar cause a chemical reaction called sodium bicarbonate. Vinegar is made up of water (h20) and 5 percent acetic acid. This combination creates an acidic chemical. When it is combined with baking soda it creates a new chemical called carbonic acid. The carbonic acid then decomposes creating carbon dioxide gas, which in turn makes bubbles. The bubbles then fill the receptacle (bag, balloon, etc.) with air until the pressure becomes too intense and an explosion occurs.

Well this month we have found a fun way to highlight this explosion with a baking soda bomb. Thanks to Homeschooljournal-Bergblog for sharing this awesome tutorial. Bergblog is written and managed by a homeschooling mom Phyllis, who teaches her four sons at home. Her blog is filled with lots of great homeschooling, educational, and fun ideas for things to do with boys. So check her out for some more great ideas.

Baking Soda Bombs

What You Will Need:

Plastic ziplock bag
Water
Vinegar
Baking soda
Paper towel

What You Will Do:

1. Tear your paper towel into a 5×5 inch square. Then place 1 1/2 tablespoons of baking soda into the middle of the square. Now fold the sides of the square into the middle to create a packet. This will be the time release packet.
2. Now using your plastic bag pour in 1/2 cup of vinegar and a 1/4 cup of warm water.
3. Begin zipping the bag closed. Wen it is half closed drop your time release baking soda packet in and quickly close the rest of the bag.
4. Shake the bag a little and then place it on the ground. Watch as it begins to fill with air as the baking soda and vinegar react. The bag will fill with air until it bursts with a very satisfying POP!

This fun and educational activity can be repeated many times, and if your boys are anything like most boys it will be!
