Apologies for not thinking of a better title, but this life hack revolves around the many uses for velcro in your house. Specifically, I am referring to velcro discs like the ones shown below. These discs have an adhesive on one side and velcro on the other. You can get a 75 pack of these velcro discs for $6 on Amazon here: VELCRO Brand – Thin Clear Fasteners | Perfect for Home or Office | 5/8in Coins | Pack of 75

The life hack part of the velcro circles is using these to hang up things which are lightweight in your house. For example, I have a whiteboard in my house and I hang up a pen and eraser for the whiteboard using velcro discs. Below is how this looks.

Basically any light weight thing in your house can be hung up with velcro. There are a lot of possibilities, such as keys, flashlights, utensils, toys, etc. Also, you can use velcro to secure various things in your house, such as cabinet door, etcs. In the video below I describe how you can use velcro in your house in more detail.
