Tsunami and Gas videos

These videos are from earlier weeks. I have forgotten to post them until now but here they are.

Gasy experience

This week we worked with gases and different chemicals to make gases and see how they react with fire and how other things react with each other.

This is yeast and warm water. Eventually the gases being produced will inflate the balloon.

These are hydrochloric acid and zinc. The gases filled the balloon.

I blew up this balloon and we put zinc in it and mixed it with oxygen when we lit it it exploded there was an actual explosion we saw the fire and everything. It was really cool.

We put the egg shell in Vinegar and the other in hydrochloric acid to see which one would dissolve the eggshell. The hydrochloric one made it float and started dissolving the egg shell.

We are starting to make rock candy flavored with mints.
