While you are down at the beach, make an impression of your foot in the sand, fill your bucket with water, add the plaster, then poor in your impression and out will come a perfectly formed sandy foot.
Bring your finished cast to school for show and tell, then keep it. Children love to watch how their body grows and it is fun for them to compare in years to come. Get them to write a little story about their holiday and keep it with their sandy foot.
The kit contains enough plaster for 2 kids foot impressions, string to hang your foot, measuring cup and reusable bucket
