Good afternoon brains trust
Year 11 Chemistry students are doing their individual depth study assessments.
One student wants to do elephant toothpaste.
My gut instinct says no but I would like your thoughts

I'm with you on that one, what are they hoping to learn and/or achieve by making it?
We have said no to students in the past for this reason.

I found this on the Steve Spangler website so will use smaller amount

We always use the yeast-H2O2-detergent one as it's safer for everyone and clean up is easier for me.
What is the student going to study via this experiment? If it was one of ours, I'd probably accuse him/her of a non serious attempt!!

Changing parameters in Elephants Toothpaste is a pretty basic individual investigation. Our low year 7 kids would do something like this, I wouldn't suggest a year 11 do it if they wanted to pass.
