Science Buddies: "Ask an Expert"

Hello. Can you please tell me how to test a bandage that I've made that uses ph to determine the stage of the wound and when to change it other than injure myself? Thanks.

Anagra,

Thank you for using the Science Buddies fora. It is true that it is a bad idea to harm yourself, even in the name of science.

Mayhap you could purchase some blood from a butcher and let it pool and clot, simulating a "wound?"

That's all I can think of at the moment.


I hope this helps. Good luck.
