Use masking to create night-time silhouette pictures.

You will need:
  • A sheet of black paper or card
  • An old toothbrush
  • Paint
  • A photograph of a landmark
  • Scissors
  • Cereal box card
First choose a good picture with a clear outline - like this one of London's Tower Bridge.
Either cut out the outline of the photo or trace around it onto some cereal box card, so you can then cut it out.
Place the outline on the black paper.
Mix some white poster paint with a bit of water so that it's slightly runny.

Dip the old toothbrush into it, and tap off the drips.
Take a scrap of card and flick the bristles of the brush away from you, so the paint splatters onto the picture.
This should create a starry effect.

The card silhouette is masking the paper so the paint doesn't get to it.
Let the paint dry, then remove the mask.
Now to create your firework effect.

Place the card mask exactly where it was. Then, using a few different brightly coloured paints, dab on some bigger blobs and splodges wherever you like.
Dab on some dust trails.
With the tip of your brush handle, scratch around over the splodges to create sparks from the firework.
Again, let the paint dry and carefully remove the mask.
You can experiment with different masks - this one is New York!

Try it yourself!
