The Chemistry Lab is open daily, 10am-5pm. Hours are subject to change.
The Chemistry Lab is open to guests of all ages who are excited to do chemistry while wearing goggles and following instructions.
Everyone must wear goggles to protect their eyes from chemicals. You can choose from two sizes and a variety of colors. The straps are adjustable and the goggles fit over glasses, so they will fit most people. Our ultraviolet sanitization cabinet sterilizes goggles after each use. Chemistry Lab staff are happy to help with any goggle needs.
There are always staff and volunteers in the lab who are excited to help.
