How to make a Harry Potter lighting scar? Answered
A grandson will go as Harry Potter.
I would like to make a scar to spirit gum to his forehead.
As a kicker I plan to put an smd LED under the appliance.
Powered by a flat cell in the hair and fine magnet wire for conductors.
So far I was planing to use a glue gun to form the scar on a tin can
for simulated forehead curved shape..
Any suggestions on a better material or kit will be greatly appreciated !
