Grownups, we’re proud to bring free, high-quality educational podcasts to families and classrooms everywhere. But as the media industry changes, it’s becoming increasingly difficult to financially sustain high-quality human-made audio shows like ours without additional help. If our shows have sparked wonder, laughter, or curiosity for your family, we’re asking for your support now.

Grownups, you can give what you can, or visit tinkercast.com/support where you can select from a handful of gifts we’ve curated to thank you for your support.
