Is this Subaru 'colour change prank' real or fake?

Did they double prank us?

The prank is explained like this: the Subaru sedan is coated in something called ‘Paramagnetic paint’ that changes colour when electricity is passed through it. A couple of pranksters hide nearby and scare passers by.

BUT, the pranksters double prank us because, really, if a paint could change colour would it be as quickly as that? No…

The supposed victims are actually actors and some of their acting skills are a little over the top. We think this gives it away.
