Glass Sippy Cup
Handmade glass smoothie straw from Glass Dharma and my dear canning jar is back again. I drilled a hole in the lid with my Dremel (a girl's BF) and then used the grinding and sanding attachments. I finished off by hand sanding the hole (finger wrapped in sandpaper) so it became nice and smooth and less sharpy-knife-like. It really was super sharp so make sure you don't slice your finggy off.
*still some plastic coating on the lid :(
They actually make BPA-free real sippy cup lids for canning jars! Also, Tattler makes BPA-free lids - hmm... now I'm thinking of getting the sampler pack and drilling a hole in one of these.
