Wayne Berendhuysen from EHV Props is the creator of a very smart cosplay suit created around Mark 39 variant of Tony Stark’s suit. This suit uses gas particles and 10- watt floodlight LEDs to simulate the effect of thrusters coming out of his hands and jetpack.
Over the years of travelling to Comic Con and seeing what people have created, this suit has to be one of the best creations to date that I have seen. The effects of the suit look incredible and the hard work and dedication that went in to suit is shown by the final outcome. A short YouTube clip below shows the suit in full use!
