Let's find out, grade 2; Sparks

Now when my two boys and girls to listen your science let me bring you another program. I know boys and girls. What do you suppose we're going to do with all that you have there on your table today. Somebody may have guessed but let's get ready right away to use them shall we. Mr. Sparks and Miss static Are you at the table ready to begin. Well if you are pick up the towel and dry your hands. We need very dry hands to do our experiments today. Be sure the palms of your hands are dry. Rub your hands on the towel and get them very dry. Now while you're drying your hands let's ask your teacher to make sure that the balloon

is blown up and tied so that no air can come out of it. Maybe your balloon is already blown full of air and that's fine. But if it isn't a teacher will you please blow it up and tie it so that it will be ready for us to use a little later. Thank you. Well your hands are to be dry by now Mr Sparks and miss that ache. Are they good. Mr. Sparks will you pick up the comb. Take a good look at that comb hone it out so everyone can see it. Most of you have seen a comb like that one before haven't you. He has served most of you have a comb very much like that one. So what do you use a comb. I hope so. Well Mr Sparks home of the column in one hand and pick up the piece of wool in your other hand.

Pick up whatever you have there you may have a mitten are a little piece of woolen cloth anything that made a rule pick it up in your other hand. Now rub the comb as hard as you can with a piece of wool. Wait just a minute maybe we better all do this the same way. Hold the cone near one and Mr. Sparks. Near one end of the go and rub the back this smooth side of the comb with your top with the ruined piece of goods you don't have to rub hard and fast. All right now go ahead and rub and keep on rubbing until I tell you to stop. Now well Mr Sparks is rubbing the comb with static rooms spread out some of those small bits of tissue paper on the table. See if each piece can be by itself. Put them somewhere near the center of the table. You are right Mr. Sparks are you already. You

can stop rubbing the comb now. Are you tired. Now very carefully touch just one piece of paper with the end of the comb. Did anything happen. The paper stuck to the comb here in the studio did yours. How about trying that again this time to be sure that you do not touch the comb against anything until you try to touch the paper with it. Pick up the world again and rub the comb with it. You won't have to read too long this time. Are you reading it right now don't touch the comb against your other hand or anything else but very carefully put the comb down against a little piece of paper through the paper here almost jumped up to the comb. Through three pieces. Did yours.

Well it ought to work. Now if yours didn't when you tried again after the broadcast good some time you must try this experiment several times before it will work just right. But your good scientists aren't you. And good scientists try things over and over again to be sure they're doing them just right. And if you are doing it just right. If your hands are dry and a comb is dry and the little pieces of paper are dry you won't be able to make that work. Be sure your hands are dry and be sure the comb is dry too. All right well let's put the comb down on the table. Now if you saw those little pieces of paper stick to the comb that Mr. Sparks held in his hand you saw static electricity do it trick for you. You made electricity. Shall we try something else.

Now push the comb in the little pieces of paper over on one side of the table out of the way. Miss static. Let's see what you can do for us to see. I miss that ache when you pick up the piece of cellophane please hold it up so everyone can see it. We see cellophane almost every day somewhere or other don't we. We get lots of things in cellophane bags now. Now today we're going to see if cellophane will help us make some static electricity. Miss Derrick hold the piece of self right first of all. You better wipe your hands on the towel again be sure they're dry right now. Hold the piece of cellophane like cellophane. That's a hard word to say cellophane flat down flat on the table and hold it with both hands one hand at each

end of the piece. Are you ready. Are you holding it tight. All right Mr. Sparks will you pick up the piece of rolling material and rub this cellophane strip with it rub the roll from one end of the cellophane to the other and several times. Don't stop now rub fast. That ought to be enough. Now lift off the woolen cloth miss static. Pick up the piece of cellophane luar piece of cellophane is sticking to miss statics bring your needed stick to the tabletop too. Was it hard to pull off the top of the table. Well can you shake it off your fingers in a static try. Or sometimes a cellophane seems to stick right to your hands. Missed attic rock or ridge is somewhere near you and give the cellophane to them.

Did it stick to his fans too. Sometimes ordinary paper the paper that you write on at school will work for you too. Will you try a piece after the broadcast. Good for you. Now let's try something else you can try the cellophane again a little bit later. Let's try something with the balloon. First of all both of you dry your hands again on the towel. When we work with static electricity we have to have dry hand. And I hope the air in your room is pretty dry. If it isn't maybe these experiments won't work today but you'll try it another day won't you. Good. Now both of you are your hands dry here they're really dry. All right Mr. Herrick. Pick up the balloon and hold it between two hands. Put a hold the little opening the little the stem of the balloon in one hand and then put your other hand up at the top.

The opposite side of that stamina hold the balloon tight. Now Mr. Sparks pick up the woolen cloth and rub it over the whole surface of the balloon. Rub all over the outside of the balloon with that cloth. Misdoubt it hold it steady with your fingers so that Mr. Sparks can rub it. All right. Do a good job of rubbing that balloon with a woollen material. He rubbed it all around on all sides. All right now that ought to be enough. Miss park take the balloon over to the wall not the blackboard find a piece of wall in your room. See if the balloon will stick to the wall put it up against the wall. Do you think. Well you made electricity by rubbing the balloon with the woolen cloth. It stuck to the wall because you made the balloon static with electricity. Take it off

the wall miss daddy. Go back over to Mr. Barch will you. Mr. Sparks rubbed the balloon again with the wall. Hold it tight now so it won't fall out of your hands. Alright now rub it all around as much as you can go a whole surface of that balloon. And he rubbed it enough do you think. All right take them all away now Miss static put the balloon up against Mr. Sparks face up against his cheek. It degrees be. All ours did here in this beauty oh wells daddy electricity is fun to play with isn't it. You couldn't see the static but you could see what it did. Can you hear static. How many of you have ever heard static on your radio or on your television. Static electricity can make a noise sometimes that we can hear. Have you

ever heard static sound on your telephone. Have you ever seen lightning jump from one cloud to another during its a thunderstorm. Lightning is caused by static electricity. Did You Know That. There it is now after the broadcast. You may want to talk about static electricity where you heard it where you have seen what it can do. Now let's think what you do to the comb before it would pick up the pieces of tissue paper. What did you do to the cellophane before it would stick to your fingers. What did you do to the balloon before it would stick to the wall or do Mr. Sparks face. Why don't you try some other things. Not all things will work but

you could try them and find out couldn't you. When you do that let me tell you another thing that you can try maybe you could drive right there who has a very clean hair is there someone in the room that washed their hair last night. Well if someone thinks he has a very clean dry hair come up to the front of the room just one teacher when you pick out one please quickly come up to the front of the room and I wonder if teacher will do this for us because I think she's taller and she'll be able to do it easier. Teacher When you pick up the comb off the table and call the person's hair who has a very clean dry hair rub the comb through it several times very fast what's happening to that hair. Is it standing up. Teacher put the comb rub the comb through here once more. Two or three times. Now see if the if the person's hair will

jump up to the comb when you put the comb near it. Well you could try that too but your hair has to be very clean and very very dry before it will do that. Have you ever walked across the heavy carpet and then touched the wall or someone else and felt a tingle ice block on your finger. That static electricity to where you try it and where you try is making static electricity with many other things and see which one of the things that you drive will really work. When you do this. Oh right. Let's find out imagine night in the studios of Allen St.

Louis Board of Education radio saying. This is the end I would be a radio network.
