So they Steep better in the sun. Hum, mine are in a dark bedroom in a cabinet.
You can use heat and shaking to steep a juice (I've even heard of people giving juices a quick blast in a microwave, but don't think I'd want to try this myself).
Or you can just leave the juice un-capped in a dark place and give them a daily shake to get things moving - obviously put the cap on before shaking though, or it might get messy
