Making Elephant Toothpaste is as simple as mixing two chemicals – causing an explosion of foamy science goodness. We take a look at two reactions with hydrog…

Thumbs up if you go to SLC!!!

Dat elephant’s toothpaste :B

this is so awesome love it.

I use it all the time on my food.

In this demo? Not really. This is a special chemical reaction….

this kind of a crazy question but can you use salt

I have no problem if you embed the video from YouTube on a page somewhere. If you want to host the video on another site somewhere you need to tell me more details…

Can I use this video for a project I’m doing? :D
It’s going to be an online project :)

YOU JUST MADE MY HOMEWORK SO MUCH EASIER JUST BY LOOKING AT YOU DO YOUR WORK

It is how much of something you put in a liquid. LOTS of sugar in a little bit of water is a HIGH concentration. Just a SMALL amount of sugar in LOTS of water is a LOW concentration.

so epic!


WHAT DOES CONCENTRATION MEANS? I SEARCHED IT UP AND IT MAKES NO SENSE.

getting high on oxygen i see XD

Check with local authorities. It often depends on concentrations, etc… (for example, HCl can be neutralized to become water and a salt…) Also look up the safety information available from whoever sold you the chemicals. Most companies now have handy databases to help with disposal issues.

Cool! 2:57

question: how do you dispose hcl and sodium thiosulfate? can you pour them down the drain?

Think of making frozen orange juice. When it is in the can, it is a certain amount of orange. When you put it in a pitcher and add water, it is still the same amount of orange, there is just more water there, too.  So the Concentration of orange changed, not how much orange is present.

what is the difference of how much and the concentration of the substance?

i can see one of caspers enemy in da last experiment 3:13 to 3:24

An explosion can often be thought of as a really, really fast reaction.

At some point it would be dangerous and explosive. 100% hydrogen peroxide would probably be too unstable to even sit by itself (if you could even make it.)

how would the reaction look if it were 100% hydrogen peroxide? Would it go so fast as to be explosive, or would it just do the same “toothpaste” effect but at an even faster rate?

If you look around the internet for the science demo “Elephant Toothpaste”, you should find a list of the ingredients and directions.

hello, hmm can u please tell me the measurments u used and the products u used thank u

thanks! :)

Well, this video touches on it, but I’ll think about it! My goal is to avoid the math portions just to focus in on the main conceptual parts of things as much as possible.
