Now a real comment, after spamming all the comments to your post (having discovered the placenta-eating 'trend' (or name this as you want) on Steem... I had too ;)

Thanks a lot for sharing this kind of material on steemstem. This is the kind of stuff that will make us different from any other platform on the web! On top of being very cool for your student. Being able to manipulate and do experiments going beyond the books (which seems to be the case here) is how we will attract students into science and hopefully create vocation.

PS: I assume you will have to find a placenta for every year now :p
