Step 1: Add the following to a large zip lock bag:
- Shaving cream
- (the more shaving cream one uses, the larger the zip lock bag will need to be)
- Use 2 cups shaving cream for 30 centimeter x 20 centimeter bags
- 2 tablespoons food coloring
Step 2: Seal the zip lock bag completely.
Step 3: Have the child very carefully start massaging the bag to spread the color so it mixes with the shaving cream.
Step 4: Start writing.
