I have a test tomorrow morning, so I've wanted to heat and practice stowing my bottle of QF so I was good to go tomorrow morning.

I heat it in the microwave for 10s, stopped, then another ten (it bubbled slightly at the end), but when I removed it, even though the bottle was quite warm, the temp strip read black.

So what is the best, cheapest way to work around this? Get a digital thermometer?

Just want to make sure I'm good to go - it felt quite warm, and my plan was to take it out of the microwave, rubber band the heating back to it, and stow it between two pairs of boxer briefs.
