Our waterproof flashlights are going very well. We are making the blueprints and some are even making the circuits already! I am almost ready to finish my circuits! I have my blueprints done and I am doing my wires just before putting it all together and making the circuits. My measurements are 10 inches, 6 and a half inches and four inches.  I also have all of my pipes measured for when I cut them. Its going great and I will have a flashlight that works underwater!
