Today, I am gonna do my final of three red hot knife videos,ggdgb after the poll I did last week showed 82% wanted to see more. And we’re gonna start with a sponge. Well, not just one, I am going to stack four on top of each other. When I heat up the knife, you can see it goes straight through them. Almost like butt! It’s really quite amazing so I’ll show you again. Because the sponge is so light and obviously full of air, it cuts through it really easily, and it doesn’t cool down the blades too quickly. But after this second cut, look what happens. The blade had cooled down too much to cut it, instead it just compressed the sponge. Then it sprung out and went flying everywhere. But it did leave me with these handy sized piece of sponge. If I try cutting something which is really dense instead, like a bar of soap, you can see it takes a long time to cut through. I’m having to push down quite hard here. And finally I get to the bottom It’s cooled the blade down too much for a second cut, so I have to heat it up again. *Squeaking noise* *BANG!* I wanted to try cutting a tennis ball in half. But as you can see it struggled to get through the thick layer of rubber. So I heated up the blade again. Then managed to push the tip through. Then I could cut all the way down. You can see just how thick the rubber is. And I might use these in a future project somewhere. And finally I decided to try cutting through my running trainers. Although these weren’t very old, they were very cheap. And they started to come apart on the sole where the toe flexes. And the padding of the heel had perished so they rubbed on the back of my ankle. So I replaced them with some better quality ones. But I am keeping the insoles, as these are really comfy. So I heated up the knife. and cut straight through You can see it sets fire to the top layer pretty quickly, And cuts through the sole with hardly any effort. I cut in front of the laces, so I can still use them if I want And that’s the cross-section of our shoe. And these are going to be perfect for the summer to stop my feet from getting too hot Pretty cool huh!
