We sometimes think of scientists as calculated, precise people in white lab coats, buzzing around their controlled experiments and complicated models. But as anyone who’s actually worked in science will tell you, field work is often messy – incredibly messy for that matter. A new hashtag has taken Twitter by storm: #FieldWorkFail. Here are some of the best ones.

First off, it’s the crocs:

Accidentally glued myself to a crocodile while attaching a radio transmitter. #fieldworkfail

I should add that the croc lost the transmitter within 24h. Was supposed to stay on for a month. #fieldworkfail https://t.co/ICKSFUFEgd — Agata Staniewicz (@AgataStaniewicz) August 2, 2015

As it turns out, Agata had even more fieldwork fail moments with crocs, but thankfully, nothing bad happened:

Turns out, biologists often have a bad time in the field:

1988: Went to Jamaica to collect insects. Hurricane Gilbert also went to Jamaica. Our insect traps probably went to Mexico #fieldworkfail — Terry Wheeler (@ta_wheeler) July 31, 2015

Skillfully applied thousand dollar satellite tag to manta ray. The same manta ray I tagged yesterday #fieldworkfail pic.twitter.com/xHR1agskar — Dr. Alistair Dove (@AlistairDove) July 31, 2015

Sometimes, the fails can become really dangerous.

Accidentally pee on a Jaguar´s marked tree. Get chased by the jaguar for 3 weeks, might sound exciting, actually quite scary #fieldworkfails

Any respectable geologist has had his fair share of fails.

Rough, passing supplies from boat. Case of beer fell in sea. Dangled field leader by ankles. Retrieved beer, lost leader. #fieldworkfail ? — Hannah Grist (@hgloki) July 31, 2015

We may have put a wee bit too much tracer in the river. #FieldWorkFail pic.twitter.com/TACp1SPxwG

Caught in thunderstorm, ditched metal auger to be safe. When I got back remembered I was wearing GPS backpack with 3m aerial. #fieldworkfail

Once I got very excited to find some bones in a trench, thinking it may have been a midden, then the KFC wrapper emerged. #fieldworkfails

The hashtag is just spectacular – it shows just how down to earth scientists can be, it humanizes them, and it’s really funny.

You know #FieldworkFail is really cool evidence that lots of dedicated people are busting butt trying to do v. difficult things for #Science

This #FieldWorkFail hashtag is great. I love how unglamorous science can be.

I am pleased at how many #fieldworkfail posts involve exposed butt cracks. And pee. I want to be a scientist.
