The above is how you can prove "Magic" still works.
The biggest problem is we have forgotten most of the spells.
Magic can be defined as "Causing a change in the physical universe through the use of gesture and incantation".
This can be proven empirically by the following experiment:-
Carry out the actions in the last part of the above post.
Then wave the hand around and say "Oh golly, Oh gosh, by crikey"
Nothing happens, wrong gesture and wrong incantation.
However, if you thrust the throbbing thumb into the mouth and suck hard and shout loudly as many strong swear words as possible the pain miraculously dissipates thus proving the correct gesture and incantation was used which caused a positive change in the physical universe.
This is white magic at work because its a positive change rather than black magic at work which would cause a negative change and end up hurting more.
Science has now come to realise the above is all true and have proven it in the same manner.
Scientists have just proven the unique power of swearing by inventing fake obscenities and comparing them to the classics.
