Pocket Flashlight

I follow the pocket flashlight tutorial online, and here is the link:

I choose to make a pocket flashlight because it is convenient and easy to make.

The materials I need are:

• coin battery
• led light
• self-adhesive foam
• ruler 
• pencil
• knife

First, I cut off a circle with the
size of coin battery from
1.5 inches *1.5 inches
foam pieces, and then I
insert the battery into it.

Then, I cut off a piece
of 1.5inches*1.5 inches
paper and the same size
foam. I stick them on
the back and forth of the
flashlight.

Finally, I use taps to decorate the flashlight. When I squeeze
the flashlight, it lights up.
