Lightbulbs are becoming cheaper because they are been replaced by cold light lamps and LEDÂ´s .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 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¡)
