Lol…I’ve done that…in a real lab, too, where there were a bunch of crazy chemicals with 100-character long names that have to be disposed of in special airtight disposal cans that have “toxic waste” and crossbones printed across. So I was supposed to do something with a can of NaCl solution but being a stupid idiot, I forgot to label the jar of NaCl so instead of NaCl I could have possibly taken a can of…anything else in the lab. So not wanting to get in more trouble for having messed up every experiment I’ve tried so far, I decided that I could easily see if the solution was NaCl by tasting it…if it was salty, then it was NaCl, and if it wasn’t…then it wasn’t NaCl. So I did, and luckily it was NaCl solution =)</p>
