A day of Chemistry..

Today I had a great day in the lab trying out a bunch of demo’s that I’m hoping to use as a teacher. We started off by making some Oxygen, Hydrogen and Carbon Dioxide… which was all a bit easy and then the fun started!

The first one was a simple but cool use of a pop bottle filled with hydrogen and air…

Getting more exotic we moved on to the oddly called the Elephant’s toothpaste. This is the rapid decomposition of hydrogen peroxide and result in quite “volcano” of foam:

This was then followed of by the “Whoosh Bottle” which is an example of a rapid combustion reaction:

Note: I’d really not recommend doing any of these outside a proper lab and without the appropriate training and risk assessment. Lots of fun though.
