And that sugar dough?

looking at different Play Doh recipes.

This is natural from the environment, this clay.

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

Women also work with clay to produce pottery, using improved and stabilized clay kilns, and they also use kaolin to make paint in rural areas.

And so we spent a summer looking at different Play Doh recipes.

Well it's 150 times more resistant to electric current than that salt dough.

In fact, I could even add some movement to my sculptures.

And they're great. We can make great little sculptures with these.

Right, the current wants to run through the play dough, not through that LED.

For example, in this case, RNA, shown in red

I bought some Super Sculpeys, some armature wire, some various materials.

And I looked down at this Sculpey, and I thought, maybe, yeah, maybe I could make my own dodo skull.

If I place that between, now all the dough is touching, but if I stick that light back in,

So I would encourage you all to grab some Play Doh, grab some salt, grab some sugar and start playing.

Certain kind of molecules like to associate with the clay. For example, in this case, RNA, shown in red this is a relative of DNA, it's an informational molecule it can come along and it starts to associate with the surface of this clay.

And there are all kinds of play clay for finger dexterity, word games for reading success, large motor play, small motor play.

If I place that between, now all the dough is touching, but if I stick that light back in, I have light.

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.

A marble is a small spherical toy usually made from glass, clay, steel, plastic or agate.

It turns out that regular Play Doh that you buy at the store conducts electricity, and high school physics teachers have used that for years.

And there are all kinds of play clay for finger dexterity, word games for reading success, large motor play, small motor play. I feel like I could devote my life to figuring out what to play with my kids.

And one day, a couple of weeks later, it might have been maybe a year later, I was in the art store with my kids, and I was buying some clay tools we were going to have a craft day.

In a zippy demo at TED U, AnnMarie Thomas shows how two different kinds of homemade play dough can be used to demonstrate electrical properties by lighting up LEDs, spinning motors, and turning little kids into circuit designers.
