EISCO PTC Taster Paper Strips - Vial of 100 | Genetic Testing Experiment | Demonstrate Effects of Heredity on Taste | - 30µg Per Strip

It works, tastes gross to me, but some others can't taste it at all

It works fine- No complaints on this product - lots of fun for the whole family ;)

These did not work at all.

My boyfriend and I have always suspected I was a supertaster due to how much more I taste in 'bland' foods and how I hate a lot of food that tastes bland to him. Sure enough, I am a supertaster and he is not. Also found out that my sister and mom are, but my dad is not. Must be genetic! Fair warning, this thing is VILE if you are a supertaster. It's like licking battery acid. Have a drink and something strong to chew on right next to you or anyone taking this as they will need it if the test is positive.

Received the package in proper condition,though delivery was a bit late but the product was good. Bought the tasting paper for a project and it actually worked.

This was a super fun experiment! Precision Laboratories sends you 100 strips of paper coated in phenylthiourea, which is a chemical that either tastes extremely bitter or like nothing depending on the taster. The ability to taste PTC is encoded by the TAS2R38 gene, which codes for a taste receptor on the tongue. This is an interesting product for educators and curious minds alike. To answer some of the questions listed above: This product does not have an ingredients list. I would assume that it is just because it is only paper and PTC, but if you have concerns I would contact the seller. The strips do not come with any instructions, and most science experiments online do not indicate any clear steps either. I would recommend not doing this experiment if you have just burnt your tongue. Other than that, just rinse your mouth out with some water, place the strip on your tongue, and close your mouth. Super tasters like me will immediately want to remove it! ***I would recommend purchasing this very early in advance if you needed it for a specific date, like for a specific class. This product was fulfilled by Amazon and I had a ton of issues getting it. I had two day shipping but it took almost two weeks because the product never arrived and then Amazon made me purchase it again myself. I was kind of annoyed with Amazon's customer service but did not want to take it out on what seems like a very reputable company!

In linea con le striscette fornite da altre marche, ma in questo caso devo dire che il barattolino rende impossibile prendere una striscetta senza toccare le altre con le dita e questo è poco igienico purtroppo quando si effettua uno screening del gusto con diverse persone.

It is very good for testing sensitivity for bitterness taste.
