For the latest Formula 1 Monaco Grand Prix race, race car driver Sebastian Vettel wore a newly designed Red Bull helmet that featured heat-triggered paint technology. The illustration shows a glamorous 20s model in her bathing suit, and when the bathing suit comes in contact with heat, it completely disappears.
When the Red Bull helmet is room temperature, the blonde glamorous pin-up model sits on her knees in a halter-top black bikini. As Sebastian Vettel wears the helmet on the course and starts to sweat, the heat coming off of his head triggers the heat-sensitive paint in the bathing suit and it begins to fade until she is entirely nude.
While the technology is a creative way to tie art and race car driving together, the use of it to reveal a naked painted model is a bit tongue-in-cheek. Lucky for those who don't approve, the drawing is located at the back of the helmet.
