I think it would be fun to test this with a few people. Let’s vacuum pack some beans and ship them between each other. Sisterhood of the Shipped Legumes.

I can confirm it. I have a commercial vacuum packing machine, and a bag of rice sealed in it becomes a brick. You can't displace a grain of rice without damaging the vacuum.
I doubt that a laptop inside this bag would survive it.
A commercial vacuum packing machine may be stronger than a normal home vacuum cleaner, which the article mentions. Fewer people have access to a commercial machine.
Yeah I was talking about the home vacuum cleaner method. The article mentions that first, but it does go on to mention vacuum packing machines too.
I could see vacuum packing machines possibly working for this.
