What does a blunt needle have in common with UV light, syringe, milk, food colorings, water, powder, high temperature, 2 engineers, a research instrument maker and an intern in a mechanical workshop?

Find a correct answer of a line manager:

A. Dunno, but such a combination sounds messy. Guys, have you cleaned afterwards?

B. Some kind of scary & weird experiment for sure. Blunt needle??! Gosh, hope they have not injured our new intern; it would not be good for PR ...

C. Whoever was in the workshop defo had fun ... wait a minute, they should be working!

D. Cannot be! Paulaaaa!! were you baking space-cake again during working hours?! ... (But how can she bake without flour??)

E. Well done, that is a very nice result, you have to publish it! IEEE, Nature, Journal of Heat Transfer Engineering, or maybe better Journal of Heat and Fluid Flow... Is your abstract already ready?

Already curious? Watch this space, the riddle will be revealed soon :)
