I am always amazed at the lengths distribution warehouse workers will go to tamper with these vs. just not tipping the shipment. I've actually seen boxes of replacement stickers on the back of a forklift during a tour. I once had a shipment come in with TiltWatches on it and someone had slid pins through the plastic right above the balls to hold them in place. I now check for holes on these.

IF you are shipping something that really needs to be rejected if tipped, cover the stickers with a panel, shipping manifest, etc. Make sure the receiver knows to remove the covering and check before signing for the package.

Those Tip'n'tells double as great makeshift earthquake sensors. https://i.imgur.com/v83aNzV.jpg

Absolutely. Receiver popping a panel to show the other set of tip'n'tells can get some great expressions.

But if the shippers are serious, and use to moving 6-7 figure equipment around, they'll expect it.

But how do you prove these indicators weren't triggered before shipping?

I usually do a walk around with a camera in the back of the truck before we button everything up.

Great, now they elevated a simple case of negligence (at best) to fraud.

If you want to prevent tampering, think inside the box. By which I mean also put these indicators on the inside of the box.

We used them on the crates we built around fab equipment when I helped dismantle a Zilog fab in Idaho. Quite a fun job for a young man. Those things were quite important to the buyers and the middle men though truth be told that sensitive equipment wasn't always handled with kids gloves.

> Another one is the Tip’n’tell system, which uses fine coloured sand and clear tape to detect tipping in one direction.

I imagine you'd have to ship these really carefully. :P

(Yeah I know you'd probably add the sand after attaching it to the package. :P )

No, they're stuck on and a piece of blocking plastic is removed once applied to "arm" them.

What's stopping them from using a plastic ball? Would it be too light?

I’d guess. High friction low weight and it might produce too many false negatives.

maybe you could push a plastic ball around with static

I wonder if static electricity could be used to move the ball and bypass the "no magnets" feature.

Doubtful, the static would traverse the plastic packaging and never touch the balls

Please don't do this here.

I’d go for something like a powerful vibrator like used in concrete settling.

Or exert some pressure onto the window, that will keep the ball from moving.
