Probably not best for running around and falling over with, but if you're careful or want to use them for props these are pretty cheap and easy.

I actually have some of these, and have used them in game. I must warn you, the glass is very, very thin.

I use these (40108, specifically) for potion bottles and they are durable as hell. I have dropped them from four or five feet up onto concrete and they bounced, bounced again and then finally came to a rest without a scratch. I have no idea how safe the larger ones are but the smaller ones are really quite strong. The only time I've heard of one breaking is when a fully grown man smashed one down onto a concrete block.
