Directions:
- Start by mixing glue, shaving cream, and food coloring in a bowl
- Mix equal parts of glue and shaving cream.
- Stir in until you get stiff peaks in it. YOu can always adjust the amounts.
- Once you have the perfect vibrant colors, start painting the inside of the watermelon.
- Take the green puffy paint and go around the outside to make the rind.
- Grab a paint brush and dip it in the black paint. Put dots all over the watermelon to make the seeds and you're done!
Note: when colors dry they turn darker.
