Homemade Chinese Lamborghini Diy Tech, Fast Boats, Silly Putty. But when you add the sugar into this amazing liquid it stops being an amazing liquid and just becomes a boring one. Another horrible Lamborghini Aventador replica recently appeared in China with this one. Because essentially custard powder is just cornflour which is essentially starch with some egg powder in it. But what I did was I mixed the milk in first and what I discovered was this non-Newtonian fluid behaviour. So here you took your custard powder, you put it in a bowl and you were supposed to mix in an amount of sugar and milk all in one go. So we are talking about the old style custard powder, not the stuff which is all mixed up. Now I can give a real example of my discovery of non-Newtonian fluids when I was probably about 8 or 9 years old and that was when I was trying to make custard on my own. If you add something like salt to the material, the salt dissolves into the Silly Putty and actually stops this sort of interaction happening. And if they're made to stop in a dynamic way, say if you hit this liquid with a force, with a hammer, you will cause it to react like a solid and that will give this weird phenomenon of cracking on the surface. This is a phenomenon called Hydrogen bonding where you have an interaction between Hydrogen and Oxygen groups on one molecule which lock on to the opposite Hydrogen and Oxygen on another molecule- essentially makes them sticky, makes them start to lock together. These long chains of essentially polymer type molecules which, sort of, partially lock together. So basically these types of fluids, these non-newtonian fluids work in a way that the molecules interact with one another. So I think, yes, gravity will take its toll but I think initially we will get a complete deluging of this crazy liquid.Įwen - Probably the easiest way I can describe this is by giving you an idea of why the Silly Putty works or similar types of materials work. But I think close to where our 17 kilometre square cube does touch the earth, I think it will probably envelop most things at that point. Ewen - OK well you're quite right, and we're not claiming that the Silly Putty would roll up the hills and certainly any bump, or tree or a plant or a building is going to act as a bit of a barrier and stop the Silly Putty enveloping it.
