Squirting Frog Tea Pet

I’ve had this adorable frog tea pet for a while and finally got around to filming a video. Most tea pets are just figurines that sit on your tea table but this one is special because it squirts water! It is made out of yixing clay but I’m not really sure how it works. I’m assuming it is some kind of heat transfer because the water that he shoots is always cool. Even with a slotted tea table, it can get quite messy but it makes for a fun tea session. Do you have any tea pets? I’d love to hear about it!
