Man pranks his grandma with wacky magic tricks -- and her reactions are priceless

London-born internet personality Julius Dein decided to prank his grandmother with some wacky and rather nasty magic tracks, like piercing his 'tongue' with a piece of toothpick. 

In the Facebook video, Julius is seen asking his unsuspecting grandmother to hold his 'hand', before throwing a plastic severed bloody hand at her. 

The poor old lady let out a loud scream and shouted at her grandson, "Stupid!" 

The icing on the cake was definitely Julius sticking a fire shooter on his Samsung phone and scaring his grandmother into thinking that his phone had exploded. 

What a way to scare your grandmother, Julius. You can check out the hilarious video below.
