How TF do I get my solar rocks hot enough? I've tried everything, even leaving them in the sun for 6 hours and they just don't get hot enough to cook with. Is there some trick to this or did I just get bad ones?
You just need a magnifying glass. Incidentally, have you ever had sun tea? It's where you put a bunch of tea bags in a jar and leave it out in the fucking sun all day in 100 degree heat. It's a thing people do in the South.
>>22016279 It's probably less unsafe if you start with really sterile equipment and don't let it go for long, but the tea itself you can't really control and it's probably not that clean.
