I think no one will answer by question correctly but if anyone does i would appreciate it so much that I'd give you 5 stars, a thanks, and brainliest. My question: Why are homemade thermometers not very useful.

why they are usually not homemade cause it could tell you the wrong temp outside and lots of people that made them homemade did not work out that is why you don't make homemade temp

it will show up when more than one person gives an answer

are there answer choices to this particular question?
