So there is a possibility that it might burn faster than the water repellent. But there still is a reason of doubt that the spray starch might burn faster than the water repellent. I chose the water repellent because the canister said it was extremely flammable. The size of cotton fabric. The amount of spray to put on.
All samples have same amount of drying time.
The Manipulated variable was the type of spray applied to the experimental groups. There are six experimental groups and two control tests. The controlled tests are the tests that sprays will not be applied. The tests will be on ten, 10cmx10cm squares on each type of cotton. Two other tests with the same amount and size of the controlled test will be with the Niagara Spray starch.
