Get cool at Tulsa Zoo this weekend with ice-cold creature enrichment like blood popsicles for the lions, human cooling stations that’ll help beat the heat, and even new water features. Another chilly option: Hang out in the air-conditioned BOK Pavilion and the animals will come to you with special animal chats throughout the day. Bonus: Admission is half-price 7am-9pm. Open through 5pm.
