Tarantula Water Dish

My son needed a water dish for his new pet tarantula. We were told that a lid off of a Gatorade bottle would work, but I decided to try and design one. This is what I came up with.

Please be sure to use a material that is nontoxic if you decide to make this for your pet. I cannot be held responsible for injury of death of an animal because someone did not use correct materials to make.
