I came across a video showing an interesting way of hiding your valuables, which can include seed phrases or hardware wallets. A fake bathroom tile with a drawer inside of the wall. The drawer is controlled remotely and pops out with the press of a button. You can then pull it out.
The drawer is neatly concealed and hard to spot. At least that's how it looks in the video.
Before you watch the video, try to guess which one is the fake tile on the wall? Can you spot it?
It is impossible to determine which of the tiles is fake, because the tile outline (joints) are sealed with sealant, which makes all the tiles the same. From a visual point of view, it is impossible to determine where the hidden drawer is.
But there are other methods: for example, tapping the tile, which will allow you to determine the voids, as well as a metal detector (the presence of metal elements).
In general, a rather interesting and useful method for making a hidden drawer, a small drawback of which is the need to re-seal (to smear) the outline with sealant after each opening (in general, this is not critical and can be easily solved), and also, how to open it if the battery runs out or oxidizes (may happen in 20 years
)?
I would make some minor changes to the design: add a thickened wall to the front part (behind the tile), similar in structure to a concrete wall (I'll have to experiment with materials), so that this tile doesn't knocked with an empty sound, but at the same time so that it doesn't affect the ability of the drawer to slide out due to the shifted center of gravity. Overall, I think it is a useful solution with a drawer behind the tile, which everyone can individually modernize based on their needs.
