Lightbulbs are becoming cheaper because they are been replaced by cold light lamps and LEDÂ´s .
So ,if you you have two fused lightbulbs ,reuse them into.. an hourglass!!!!
Step 1: The Materials
- Two lightbulbs of the same type
- Sand, preferably from the sea shore.
- A screw
- Some wood
- An empty can or any piece of thin metal,alluminun works great.
- Some paint for the base.
- Hidrochloric acid (you can avoid this if your sand is clean)
Step 2: The Tools
- A saw
- A pin
- A hammer
- A screwdriver
- Some sandpaper
- A pair of scisssors
- a diamond tool for rototool , one of those use for cutting glass and ceramics.
Step 3: Cutting the Metal Cap
Or you can heat it so the cement will decompose and the cap fall off.
Step 4: Cutting the Neck
Step 5: Preparing the Sand (avoid If You Want)
The sand inside the hourglass will pass through a small orifice so it is better if is clean and with homogenous diameter.
Step 6: The Chem Lab!!!
Slowly, add the acid, BE VERY CAREFUL, USE GLOVES AND A ROOM WITH CIRCULATING AIR,
Decomposing the shell is a quite safe process that only produces bubbling CO2 but the foam can overflow.
Once the bubbling ends , rinse and clean with water until all the mud is out.
Step 7: The Base
The passing hole is for holding the arm.
Then I fill it with melted lead. (again be careful because it is HOTÂ¡)
Step 8: The Collar and the Sand
Fill the bulb with the dry and clean sand
Place the disc over the hole and fix it with a bit of glue.
Now you can put it inside an oven to remove all partial humidity it can remind if you work in an humid area as I do.
Place the second bulb on top of the first one. NOW, THE NEXT STEP IS THE NO RETURN POINT SO YOU MUST BE COMPLETLY SURE OF ALL THE PREVIOUS STEPS .
Glue with with epoxi.
When dry , wrap some cotton thread or fabric., so it will look nice.
Step 9: Final Step
ThatÂ´s it !
