Epruvette Crochet Hook Holder

I like to crochet on long rides,but every time I take my crochet hook with me I end up loosing it.So when I was packing to the festival I made this to hold my crochet hook while Im traveling.
I just took a glass eprouvette that was laying around in my room,it has a little lid.I brought it home from the hospital where I was working.
I started with a magic ring,slipped it on the end of the eprouvette and kept crocheting around until it was covered.
Now I just drop my crochet hooks inside,close the lid and I can carry it where ever I want.
