Step 4: Make the Bubble Cockpit
Use progressively larger drill bits to enlarge the cockpit window. Use a cutting bit to further the expand the hole.
Cut a old CD in half and use tape to remove the silvering. Place a piece of the CD over the back side of the rocket. Use a heat gun to soften the CD so that forms in and through the window.
Use a cutting bur to shape the CD window down to size.
