Watch Ice Crystals Form in Supercooled Water! @wbreslyn

Uploaded January 2025 | Updated September 2026, 2 weeks ago

I left the water out overnight in 8F weather. Because it cooled slowly in a smooth glass bottle the water became supercooled and did not freeze (it was well below the freezing point of water). When I dropped a small piece of ice in it provided a nucleation site for the freezing to begin.

You can do this with water bottles as well.

$Convert 0.25 L to mL (0.25 Liters to Milliliters) To convert 0.25 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (0.25 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (0.25 L) as a fraction over 1: 0.25 L / 1 Multiply this fraction by the conversion factor: (0.25 L / 1) * (1000 mL / 1 L) Notice that the units of Liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (0.25 * 1000) / (1 * 1) mL = 250 / 1 mL = 250 mL So, 0.25 L is equivalent to 250 milliliters. The units of Liters (L) cancel out during the conversion process, leaving only milliliters (mL) as the final unit.$
