Night Vision Goggles

I was learning about night vision goggles because we

 were wondering how do you see other people in the dark.

I found it difficult to design my night vision 

goggles because we had to add our own features to it.

I enjoyed learning about the night vision goggles because I never knew 

how it worked.

Next time I would change the colour of my night vision 

because next time I would make it for a spy.
