The Science of Fireworks

Today we paid a return visit to Knowsley Park Centre for Learning for their annual International Day.

We were China - the science of fireworks.

This time we were in the small lecture theatre with some year 5 pupils from local feeder primary schools.

We explored rockets, sparklers and the ingredients that make gunpowder.
We found out how early fireworks were made,
Here Helen shows how colours are created in fireworks with some volunteers coming out to help

We saw how iron filings make sparkles and how bright magnesium is

We  created a fireball from and unexpected fuel source - milk powder

The whoosh bottle using alcohol as a fuel was a huge surprise and a great success

and then we finished the session by all setting off party poppers - our own little explosion!
Thank you for a brilliant day and for making us so welcome
