Science Buddies: "Ask an Expert"

where did you get it?
I am having a lot of trouble finding it for my own project.

To do this assingment, I am in need of a chemical known as sodium borohydride.
Does anyone know where I can get this easily
and under $40 for 25 grams

preferably online

According to these resources, you will need to order this chemical through your teacher or school.

Good luck!

Thanks.
I didn't know about all that safety hazard stuff.

I've learnt that this chemical can get rid of the protein molecules that are formed when an egg boils, therefore unboiling it.
Do you know of anything else that can do this?

From what I can gather the reports of sodium borohydride 'unboiling' an egg come from a single article:
http://observer.guardian.co.uk/foodmont ... 23,00.html
The article reports that the process can also be done with vitamin C (ascorbic acid), but of the several reports I've seen of people trying this, I haven't found any that succeeded. The closest I've found to success is this one:

(scroll down about half way).
That's not much to go on. I'd be nervous to spend a lot of time on this experiment unless I could find some better explanations of procedures and theory. If you can't find better info, you might want to explore some other experiments in food chemistry.
Maybe our chemists here can offer some other suggestions & ideas.
