Every time I run an experiment it seems something happens and messes it all up. So to help me (and everyone else) I’ve made three little cartoons that you can print out and fold into signs too help your fellow lab mates know what your doing.
Full A4 downloadable printouts are below! Simply fold along the dotted lines to make into a nice little triangular sign. Also, and this bit is important. Take a photo and post it online (don’t together to let us know! @ErrantScience).
