Lolly scramble

It's raining and I couldn't face going out in it to find a blip, so I resorted to a packet of M&Ms and some water drops.  

It's been literally years since I tried this, and I wasn't as successful as I'd hoped I would be.  I'm darned if I can remember how I'm meant to set it up to get the refractions clear!  I'll have to do some reading up on it.

In the meantime I ate the props so no chance for a new attempt until I've been back to the supermarket.

At least it's colorful on this miserable grey day.
