Sadly, this is no longer available 'cause it was an interesting and fun experience. It certainly was unique. Many moons ago I took an Underwater Basket Weaver specialty certification.
This clever marketing specialty turned out to be a very good course as the basket had to be assembled in mid-water without touching the surface or the bottom. So, it was a superb buoyancy control exercise.
The basket I made (image below) holds the patches I received in my early certification days.

Before I retired as a biochemist, my Underwater Basket Weaver Specialty Certificate was proudly displayed in my U of Michigan office (above a framework molecular model of a dopamine D2 receptor and my 3D molecular modeling workstation).
I hope some enterprising instructor would offer this again as it is superb marketing, especially in a college town.
