here in live lab we've been making our own scribble robots today I want to show you how you can make your own one like this at home for yourself this activity was inspired by the guys at the tinkering studio so thank you very much the Exploratorium San Francisco for sharing your ideas okay so today we're going to need a plastic pot some filter pens some tape an AAA battery something to make wonky weights with so we've used plasticine an elastic band you'll also need a small motor and you might not have one of these at home but they're really easy to buy online the kind you want is a 3 volt motor I want about 2 centimeters high and they cost only a couple of pounds so our first job is to take our plastic pot doesn't matter what size and shape you have and our felt tip pens and to attach them on like robot legs so I'm just going to use this tape I'm actually going to make mine upside down with the legs sticking up to begin with I've picked some nice autumn colors today at obviously u20 these pens are going to be its legs this is what's going to make the scribble for us next we need to work out how to make it move so we need our motor and our AAA battery our first job is just going to be to check that everything is working ok with this motor it doesn't matter which way around the battery goes you just need to join up the two wires and you should be able to hear the motor spinning at the moment the motor is going to be spinning really smoothly but that's not what we want because for our scribble robot it needs to be unbalanced and shaking that's what's going to make the scribbles so we're going to use our plasti see let's make it into a bit of a lump we're going to put it on our motor a bit of a funny angle like this now to be able to hold everything in place what I've done is taken an elastic band and wrapped it around and that's going to mean you can tuck your connectors under the band and that's going to hold it nice and steady for you so now we know we can get the motor to spin in an unbalanced way we need to get it on our scribble ba to power our scribbling robot so first of all I'm going to choose where to put the battery and then I'm going to add the motor the good thing about this activity is where you put all the bits and pieces the first time around you might change your mind and try some different places as you go through the activity that's the great thing about the scribble robots you can keep chopping and changing things and seeing how that affects how it moves and the scribbles you make so let's see what kind of scribbles our robots going to make for us so I'll just take all the lids off the Pens set it down on a nice big space and then attach up the wires so even when you've got people you're happy with it doesn't have to finish therefore you're scribble but there's lots of other things you can change and see what happens to the scribbles you could change the size of your plasticine the shape of the lump where the motor is and how many pens you've got try changing all these different factors see what happens to your scribbles keep going keep making changes and see what happens happy scribbling for more activities you can try yourself at home check out these videos and for more science every week click Subscribe thanks for watching
