Where I'm planning to hide it, it won't be an issue. Also, the glass is pretty thick. You could likely drop it on the ground and it wouldn't crack. It won't just be lying on the ground somewhere or where a raccoon or some other animal could get to it. I could test the freezing temps thing in my freezer, it's an oil so I don't think it'll freeze meaning it shouldn't expand/contract depending on temperature. I moded it also so the inside where the liquid is, is completely closed off so it won't spill/leak/etc. There's a plastic tube that is inside it that keeps the log dry and it's using a wine cork to keep the inside dry. I should refine what I typed above. Oil can freeze, it just doesn't freeze at the same temperature as water would, so it should be a lot better in the cold. These are kind of just concept caches though, I could switch them up with candle wax if it does have issues when I do the freezer test run.

Are those glass? Indeed they are. I used oil scents for the liquid too, so when people open it up it'll smell like clean linen or fruit.

I haven't posted it yet as it's still a work in progress, but I'm working on making a health and mana potion themed geocache. Here's some pictures, you'll see the red one has a log in it, the blue one is kind of foamed up, but is still a work in progress. For anyone who's played any rpg games, I feel they'll have a lot of fun searching for these. It might end up being a multi-cache, not sure yet.
