Extreme Physics BBQ

Can you cook a steak with pure electricity or focussed beams of light? And can you fry a prawn with a bottle rocket? Andy invited ’’t conduct electricity very well, so the electrons have to be pushed very hard and transfer energy to the meat, in a process called joule heating. Not satisfied with that, Andy and Greg cracked out the parabolas. Parabolas focus all the incoming beams into one central focus, meaning that energy normally spread across a wide area can be harnessed to one spot of intensity. Intense enough, in fact, to singe a steak to perfection. We’ve soared through the science of whoosh bottle rockets before (click here to watch that film: https://youtu.be/_pR6w7G06tw) – could they provide the perfect platform for rapid prawn cooking? Perhaps, but there’s a projectile prawn issue to resolve first. Greg and Andy also investigated the best way to cook a steak using chemistry.
