This was really easy to make & Willa loved it! She carried it around the yard with her all afternoon.
Original recipe from http://www.smartschoolhouse.com
1 tbsp dish soap (I used gain but I think any will do)
2-3 tbsp corn starch
Start by mixing the soap with just 2 tbsp cornstarch.
Once it comes together it will be very sticky.
Keep adding more cornstarch until you can handle it without it sticking to your hands.
