Making rain squalls

After popular demand here's the recipe for my rain squalls:

Start with styrene you will probably have lying around, glue cotton balls on it (stretch them out a little)

When dry, spray lightly with grey spraypaint

Now get one of those little transparent folders to keep documents in and cut out the 'base'.

Finally I used the some excess foil people use to blind windows for bathrooms etc. This kind used static force to adhere to the window, so it had a nice thickness. Curl the edges and glue them to create some firmness and use them to balance your cloud on to simulate rain.

This is the stuff, you can probably get it at a furniture store or something

Thats it, I keep the parts seperate for easy storage. You can really crank out multiple squalls in an afternoon.
