When Someone Asks If Your Helium Is Frozen Yet

You'd be distressed too if someone asked about your frozen helium! At -269°C (4.2 Kelvin), helium has the lowest freezing point of ANY element, making it nearly impossible to solidify without extreme lab conditions. Trying to freeze helium is basically the cryogenic equivalent of trying to herd cats while blindfolded on a unicycle. Even liquid helium is bonkers enough at -269°C! So yeah, if someone casually asks if your helium is frozen yet, they're either a quantum physicist with a twisted sense of humor or they're mocking your impossible lab goals. No wonder our guy is "far from OK" - he's probably been trying to reach absolute zero for MONTHS!
