step well back yes all right three two one go
we are back with our wonderful sciency man friend dr nate and uh he is going to
be doing some incredible science stuff with us say hi dr nate hi dr nate did this before
i love it it's so great what are we going to be doing today dr nate so in that beaker just
there is something called hydrogen peroxide can i drink it no definitely do not drink this
so it's kind of like water but angry so h2o is water but this has got an extra oxygen on it so
so this is something we actually make inside of our bodies it's a poison
it's a byproduct it happens when we digest stuff so we need to get rid of it and one of
the ways we get rid of it is in our livers so i've got some chicken liver just there
you take a couple of drops of that and put it on the chicken liver it should
fizz up and that is the liver breaking down the hydrogen peroxide into water and oxygen and you
might also notice it smells really gross it does kind of smell like like chicken like like meat no
it doesn't no it's no it smells bad now the first smell was like chicken now it smells bad i don't
think i know how to smell that's what happens in our bodies but actually we can make this reaction
happen really really fast and you might have seen this before it's called the elephant's toothpaste
oh yes i hear that you really want to do the elephant's toothpaste experiment you very much
do want to do the elephant toothpaste experiment but there's one thing you have to say to the
audience at home oh do not try it at home uh not that you can anyway because you can't get the
chemicals lol but don't try at home anyway sorry and then underneath the table i'm gonna step back
you will find two flasks two flowers they are full of hydrogen peroxide and then you've got
two beakers on the right hand side that is what we're going to use to break down the
hydrogen peroxide there's also some washing up liquid and some red food coloring so first of
all give each flask a really good squirt of washing up liquid yep a bit more oh come on
there we go okay and the other one just empties it beautiful work loving your style now if you then
because i hear you quite big fans of manuela so i thought we were doing my new elephant's toothpaste
so you've got prepare just down there on the side if you use that red food coloring and then
kind of like toothpaste put big generous squirts of red food coloring down the sides of your flasks
oh that went there well that was a fail that was a big more more down the size more down the sides
i heard the unsureness okay cool that's how you fill up a pet
beautiful work i think you've got enough there yeah i'm just making sure
those beakers filled with potassium iodide that's going to break down the hydrogen peroxide
you're going to pour them in to the flask and then you are going to step
well back straight away don't even think about looking at it remember potassium iodide in and
then step well back yes all right three two one go yeah oh my god oh my gosh that is really something
wow can i hug it no oh it looks so cute look how hot it is so that steam coming off it is that it's
over 100 degrees wow now this is all cooled down we can actually touch it which is very cool and
it gives us a good perspective on just how much toothpaste an elephant actually needs so thank
you nate for showing us this and um we're going to play with this for the rest of the day i think
