$100 is a lot for 5 minutes of fun.

I read it as they were talking about the idea of having kids still go play with actual tin cans and a string in this day and age rather than it be something only old people could have done.

I just meant if they used an actual tin can and string. This is just a wired intercom. There are much cheaper ones on Amazon, several options.

Backordered until December, apparently.
