learning! diy sunscreen

I love making my own beauty products (or even just getting back to the basics of using single, natural ingredients for beauty-type purposes), and I've always wanted to try making my own sunscreen.  I already know that one of coconut oil's magical properties is supposed to be sun-resistance, and apparently the only other things I'd need are olive oil, beeswax, and zinc oxide.

For actual instructions, learn from the brilliance known as The Secret Yumiverse.  Then let's try making this together, although perhaps we'll wait until a time of year when sunscreen becomes relevant once more?  (Unless you live in Australia, then maybe do it now.  Or maybe not - with the whole ozone issue you've got going on maybe you don't want to mess with your sunscreen?)
