Richard, in the past, I've not been much of a "crafty" DIY
So, making a magnetic peanut creates some questions, the biggest
one: what kind of magnet? How strong? Does it have to be oriented properly to connect to the cup?
This was my reason for asking if one was in production. Because
I can see the potential for someone to exert tons of time, energy,
peanuts and magnets to figure it out.
