I was looking for a DIY humidifier on Google and I stumbled upon this..
Get a sandwich bag
Place a damp sponge in the bag
seal the bag and punch a few holes near the top
keep a small puddle of water in the bag at all times
Hang it somewhere (I was thinking of hanging it on the top of the tank where the crabs can't get to it

Is it safe for the crabs? I really want to do this until I can save up $60 to get a fogger.

Is there a way to circulate the humid air into the tank? Pump of any sort? If it is just a bag with water & sponge Its not going to raise the humidity.

I agree with Irene. Without air movement it's also going to be a mold paradise!

i use a small old computer fan and it helps circulate the air. also a moss pit would give them more hiding spots and help raise humidity. plus they can eat the moss! lol (it makes them have ittle green poopies! haha!)

In my crabitat, I've got a small aquarium air pump attached to some tubing which I feed into my fresh water dish. I've got the end attached to a suction cup, which I place a clean sponge on top. This helps to raise my humidity almost 10%, very cheaply! Watch out for air circulation though! Mold is all about stagnate air and lots of humidity.
