Most of the scientific discoveries that are possible with hobbyist equipment have already been made, but every once in a while a dedicated amateur will discover an unknown comet...

There are many types of hay, but many of the common ones for horses are just dried grass. Fescue, Timothy, Bermuda, and Orchard grass are all very common. You can undoubtedly just use some grass clippings from your yard or neighborhood park.

So far these have been working much better and more conveniently, but I'm interested in suggestions. Well, I think they look great, and it is awesome that you are willing to share the fruits of your labor! Being very new to microscopy I don't really have any functional suggestions, but since you ar...
