Ren Zhong is the lead scientist here. He is obsessed with pyrotechnics.If you could make any firework, like your ultimate dream firework, what would it be?Zhong has agreed to share his secret recipe for red fireworks with me.What's it like, the moment that you've designed something in the laboratoryand you get to see it explode for the first time, what does it feel like?That's magical, right? You've got the best job ever!I want to do this, I want to make them myself.Alright, so mix up and then pour down there.The mixture we made is carefully spooned into a tube.Time to find out if the recipe has worked.So this is the fun bit, this is Mr. Zhong's test facilitywhere I get to set lights to these bad boys and watch them burn.Hopefully if we got it right, these gonna be red.Put them down there. I've got a lighter. Boom!Hit the lights. This is the moment of truth. It's happening.It is red! This is it. It is actually red!
