What to do:
Step 1. Fill each of your containers with water and add a few drops of food colouring to each. You should now have 3 or 4 containers of different coloured water. Make the blue water extra-dark so your galaxy will look just like the real thing!
Step 2. Use your paintbrush to paint the inside of your jar with glitter glue. Don’t worry if it’s a little patchy – it’ll still look great! Step 3. Fill your glass jar ¼ of the way up with one of your coloured waters. Stretch out a few cotton balls so they’re wispy and pop them into the water. Use the paintbrush to poke them around until they soak up most of the water.
Step 4. Repeat with your remaining colours until the jar is full, using some blue to give your galaxy clouds a dark background. Finish by sealing the jar with its lid, and now you have a gorgeous galaxy to keep in your room!
