The office coffee machine is broken. The sharp bit that pierces the coffee pods is, well, missing.
The workaround is to stab a hole in the pods with a nail.
I figured I could go more extreme...
Step 1: Planning
In my head, I saw a stapler with stabilisers. When I did my manual thinking, it pretty much came out the same way - an arm with a spike on it to pierce the pod.
That's pretty much what I ended up with.
