Football Vanishing Spray/ Foam
The football vanishing spray became popular during the World Cup (although it was developed several years earlier). It is capable of marking a temporary white line on a pitch that disappears after only 1 minute.
Do you think this could be adapted to last for several hours (say 3-6 hours), but still disappear?
Reportedly the can contains 80% water, 17% butane gas, 1% surfactant and other ingredients including 2% vegetable oil.
“The liquified butane expands when the substance release from the can. The butane evaporates instantly forming bubbles of gas in the mixture. The surfactant causes the mixture to turn into foam. Eventually the foam disappears, leaving only water and surfactant residue on the ground.”

Any help would be much appreciated.
