It turns out that me + superglue = bad combination. First of all, I managed to get the cap glued onto the tube, so there was no way to open it again. Then I opened a new tube, and managed to get the glue all over my hands. No matter how careful I am, this aaalways happens!
So today I took a trip to town to get some rubber gloves to wear next time I use them! And afterwards I couldn't resist going into the craft store and spending all my money of course!
