  • Thank you for converting Celsius to Fahrenheit, even though you made fun of it, I'm so tired of Europeans basically telling you to google it yourself, and being all snarky, instead of being courteous, and recognizing that they have an international audience.

  • The red liquid is the same liquid they use in thermometers and it expands when it gets warmer like in a thermometer then it breaks the glass letting down the metal thing that blocks the water from coming out.

  • Usually these ampoules don't crack because of the liquid, the break because there is an air bubble inside that expands. The smaller the bubble, the higher the temperature resistence. The liquid is always the same its just colour coded in order for you to differentiate them easily.
