          Negative temperatures are hotter than any positive temperatures, think like a laser transfers heat to whatever it hits regardless of the temperature of the object

            huh, didn’t know that. thanks :)

            (although in this context, you are saying that you want an object to have temperature x, so i do believe that my interpretation is the more reasonable one)

      If only Rankin didn’t use a ° symbol as well then it would have been technically correct to just say -40°

        Fahrenheit increases at approximately twice the rate of Celsius. (ΔF=1.8ΔC), And freezing for Fahrenheit is 32° (32°F=0°C). Using these facts, we can find the conversion equation F=1.8C+32. Since this is a linear polynomial, there is exactly 1 intersection with the function F=C, which we can find by solving it as a system of equations:

        IF C=F AND F=1.8C+32 THEN C=1.8C+32.

        C=1.8C+32

        C-1.8C=32

        -.8C=32

        (-8/10)C=32

        C=32*(-10/8)

        =-32*10/8 [If you’re using a calculator, this is probably your input.]

        =-10*32/8

        =-10* (32/8)

        =-10* (2(5)/2(3))

        =-10* (2^(5-3))

        =-10* 2^2

        =-10* 2*2

        =-10* 4

        =-40

        ∴ -40°C = -40°F.

    Carpet beetles amaze me. How do they get enough moisture and nutrients to survive? Their food source is essentially inedible to any other organism, even microbes. How do they make that work?

    Most fibers can deal with a lot of heat- nuke new stuff in 140-200°f.
    And baking soda kills a lot of bugs, its good to keep some around your craft bins!

    Its good to keep your stuff air tight, and divvied up into moderately sized bins. A little bead of silicone caulk spread around the lid to make a seal solid really makes a difference, and you can get it in handheld tubes- no caulk gun.

    Ive heard too many horror stories of art history tragedies and had a room mate in college who had experienced flea trauma. I don’t want my felting to be ruined

    Aren’t you supposed to freeze it, then thaw it making believe that spring just came and then freeze those mf again to kill them and their offsprings?
