On the way home

Homeward bound after a somewhat trying day at work.

I'm not saying it wasn't enjoyable but it was trying.

Some days are like that?

A fine cycle home in pretty mild conditions.

I'm sure it won't last.

Or will it?

Teaching about the uses of ethene and ethanoic acid today. Interesting enough but it needed a bit of zing.... Alkali metals later on was more fun.

Sir, add a bigger bit! Put the whole lot in!

Crushed biscuit and potassium chlorate finale was a winner!

Sir, do it again!

We might have slipped slightly off topic....
