Adapting Football Vanishing Spray/ Foam

Adapting Football Vanishing Spray/ Foam

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.

TugboatEng - Great, thank you!

RE: Adapting Football Vanishing Spray/ Foam

I didn't read all of the way through your comment to the part where you explained how the stuff works. My first answer isn't relevant.

To make it last longer you would have to polymerize the foam. Maybe use a photodegradable polymer.
