Hello everyone! I made this for my 40 followers special, I will make more when it reach 60! I haven't post anything in awhile because the school started so I don't have that much time so I'll try to publish at least 2 instructables in a month. Enjoy the Lego Aperture science Portal gun!

Step 1: Step1: Portal Gun

This is the instruction of the portal gun, it might be a little confusing, ask me if you have any questions or leave me some comments. Please vote me if you liked it!
