In this lab, I got a plastic water bottle and left it inn the freezer for a little over an hour, when I took it out of the freezer, it was still liquid but super cold, then I whacked it against the table in my kithen, and it immediately froze.
I was really surprised when that happened, so I researched to find out how that was possible. And apparently water normally freezes at 0 °C, but when water freezes, it needs a nucleus in order for the solid crystals to form and become ice. Water is typically full of particles and impurities that will start the process of crystallization, but purified water doesn’t have those impurities. With nothing for the water molecules to latch onto, purified water can be supercooled as far as -40°C, until it's in contact with a blunt force.
Like I said, the results in this experiment really surprised me, I kind of had a feeling that that was supposed to happen, but I didn't fully believe it would work, so it was really cool when it did.
Like the previous lab, I don't think this information will ever benefit me later in life, but it's still a pretty cool party trick.
