box_of_dead_batteries_to_recycle1

For years, I have been saving dead batteries in a cardboard box. I did not want to throw the dead batteries in the trash, which then would go into the earth with some toxic waste. I learned how to recycle the batteries and it was much easier than I expected. I share the results with you.

I did an experiment, trying to clean metal in a new way (for me).  I burned some potatoes to the bottom of a pot and it needed to be cleaned.  I made the mistake of not putting in enough water and the potatoes burned at the bottom.  It was a mess and needed to be cleaned.  I decided to try an experiment and brought the camcorder with me to share the results.

The results of using hydrolysis to help clean the burned pot.

The solar lights on my property have been dim or have been completely off at night.  Maintenance can be done on these lamps to get them working again.

Making a waffle out of sodium acetate trihydrate. This is the same stuff that makes up “hot ice” and heating pads.

How is the liquid made?

Acid can release electricity from metal.  What is an easy-to-find source of acid?   Tomatoes!

VIDEO

The video above shows how an LED and a buzzer are powered by a tomato battery.  My homemade battery was made from two different metals dipped into mashed tomatoes.  This setup had low power output, but it was also able to help charge a AAA rechargeable battery.

How does this work?

Many people have tried adding Mentos to Diet Coke for a fun explosion of foam. Does only Diet Coke work or can another beverage work as well? Could Diet Pepsi work with Mentos to make an eruption?

My two kids were interested in the experiment, so for fun, we tried making our own volcano with Mentos and Diet Pepsi. It works!

We wanted to see how isopropyl alcohol vapor burns. The video below shows a few of our burns.
