Unscramble the Blue Letters

And so I want to do a little demo for you. So if I take this salt dough, again, it's like the play-dough you probably made as kids, and I plug it in — it's a two-lead battery pack, simple battery pack, you can buy them at ridao Shack and pretty much anywhere else — we can actually then light things up. But if any of you have studied electrical engineering, we can also create a sohrt circuit. If I push these together, the light turns off. Right, the current wants to run through the play-dough, not through that LED. If I separate them again, I have some light. Well now if I take that sugar dough, the sgaur duogh doesn't want to conduct electricity. It's like a wall to the electricity. If I place that between, now all the dough is touching, but if I stick that lghit back in, I have light. In fact, I could even add some movement to my sculptures. If I want a sinpning tail, let's grab a motor, put some play-dough on it, stick it on and we have spinning.

So if I take this salt dough, again, it's like the play-dough you probably made as kids, and I plug it in — it's a two-lead battery pack, simple battery pack, you can buy them at Radio Shack and pretty much anywhere else — we can actually then light things up. But if any of you have studied electrical engineering, we can also create a short circuit. If I push these together, the light turns off. Right, the current wants to run through the play-dough, not through that LED. If I separate them again, I have some light. Well now if I take that sugar dough, the sugar dough doesn't want to conduct electricity. It's like a wall to the electricity. If I place that between, now all the dough is touching, but if I stick that light back in, I have light. In fact, I could even add some movement to my sculptures.
