Begin by using white glue to draw the fireworks on black cardstock. We cut our paper in half, to make it 6 x 9 inches, but you can use a full page if you'd like.You can also draw fireworks with a pencil first, but we actually found it easier to freehand the fireworks with the glue, rather than following specific lines.
Start the firework by drawing a "seagull" style of "M" with the glue, and then draw more curved lines going off to the side and bottom. Finally, add some short unconnected lines that look like they're coming from the center.
Continue, adding more fireworks on your page, in different sizes until you've filled the paper.
Step 3: Add salt to the glue
Sprinkle the glue with a generous amount of salt, making sure all of it is covered.
Lift the paper and let the excess salt fall off.You can put the paper upside-down briefly, but don't tap or shake the paper -- it can cause too much salt to fall off, and the glue may flatten.You can re-use this salt for your next painting.
Step 4: Prepare the watercolour paint
Pour a bit of water into a deep paint palette or into small bowls (1 section or bowl per colour you want to use).
Add liquid watercolour paint to the water. Try for a 3:1 water to paint ratio. For example, 3 teaspoons of water for every 1 teaspoon of paint - but it doesn't need to be exact.
Stir the paint into the water with your paintbrush before using it.
Step 5: Add paint to the raised salt lines
Bring the brush over to the salt-covered glue and lightly touch the brush to the salt. Watch as the paint spreads, like magic, across the salt.
Continue adding a little bit of paint at a time, and enjoy watching the paint spread across the salt.
Use a new colour of paint for the next firework.Clean your brush in water between colours and make sure it's not too wet when you pick up the paint.
Continue painting until all your fireworks are bright and colourful.
You can also create different fireworks designs and use more than 1 colour of paint on the same firework.
