Those candy melt things taste simply awful (to me) - but maybe if they are for kids, they wouldn't care?
If you want, instead, you could use any kind of chocolate chips or solid chocolate bars. (I usually use Ghiradelli - have a 10 lb. bar from Trader Joe's I just chip chunks off of...) You can carefully/slowly melt them in a microwave or double-boiler (simply a pot in a pot with some water in the bottom) on the stove. If you microwave them, you can even do that in the little squeezy bottles the craft stores have next to the candy molds. If on the stove, just spoon the melted chocolate into the molds.
Couldn't be easier!
The craft stores also sell the little plastic bags to twist-tie over the finished lollipops, if you use that shape, or to package up the loose candy.
Good luck!
