For those who like seeing movies or TV on his room here it comes a one-handed try to avoid messy crumbs or drops into the room. It feets perfectly on the bedside table.

Step 1: Take All the Stuff You Want to Get to Your Room.

A napkin
A cup
Groceries or whatever you want to take
A big or medium bowl

Step 2: Put the Napkin on the Bowl

Take your napkin and place it on the bowl covering all of it.

Step 3: Place the Cup.

Place the cup on the center of the bowl, you can place it on one side, though. But, the more centered, the more stable it will be this try.

Step 4: Take the Groceries.

Take all the groceries and put them surrounding the cup you have placed on the bowl previously. Again, you can do whatever you want that gets you through the way.
