Mysterious Lightbulb Prank

Step 4 Step 2

On the second bulb, I cut away a small edge of the base. Just enough to grab it with needle nose pliers and start 'unwrapping' the base from the bulb. Shen I was done I ended up with a clean glass bulb.

Please tell me how you remove the base without breaking the glass bulb. I have tried this several times and because the bulb is a under a Vacuum Pressure it breakes and I have never seen one come apart at the base as clean as yours. I would love to know which brand you are using so I could make one Thanks Tom

I have bought cheap brandless bulbs and removed the foot as well (it was for another project).
Just hacksaw through the lower end of the metal base and then just peel off the rest of the metal with pliers.

This leaves you with a closed glass bulb haveing a glass rod stick out at the bottom.

Break off that rod.
Then immobilize a belt sander somewhere or ask someone to hold it for you and gently but firmly press the base of the lamp against the turning sandbelt,

Turn the lamp a few times as you probably will not push it sgainst the belt completely straight.

Very soon you will have gone through the base and the inner glass off the lamp will be loose and yr bulb will be open
