Ideal for use in genetics education. These PTC (Pheylthiocarbamide) paper strips are either bitter or tasteless depending on the taster's genetics. Simply touch the strip to the user's tongue and record the results; do not eat.
Pack of 100 strips.
I have done genetic testing on both me and my husband that says he would probably be able to taste PTC but I probably wouldn't and it was correct. We did blind-testing on each other :)
