Can thumbtacks found in hot coffee make you sick?

No, thumbtacks found in hot coffee will not make you sick. Thumbtacks are made of steel, which is non-toxic. The hot coffee will not dissolve the steel, so it will not be released into the coffee. Therefore, drinking hot coffee with a thumbtack in it will not cause any health problems.

However, it is important to note that thumbtacks can be sharp and could potentially cause injury if they are swallowed. Therefore, it is best to avoid drinking coffee with thumbtacks in it.
