I sent an email to one of the people who answers your snack questions - but thought I would try this address too.
I am writing to ask that you do remove your magnetic pendulum snack from the website. I tried it - with no success and judging from what I read in the "snack talk" - most people have a problem with this snack. There are also errors in the measurements - which have been brought to your attention, but obviously not corrected.
I am an elementary science teacher and have enjoyed some of your other snacks. It was very frustrating to go through the effort of building this and assembling materials - only to have it fail.
