Science Fair Summary Spray on Toothpaste

Connor and I are doing science fair on spray on toothpaste. We wanted to create a spray toothpaste as hinted in the name. We created the spray on toothpaste because it would be easier to get all the toothpaste out of the tube because there is always some in the bottom. We created the the name of the spray on toothpaste which is Oral Fresh. The can is decorated can with the prices on the side of it, which is  $8.00 for a new one and $5.00 for a refill.
