Lightbulbs are becoming cheaper because they are been replaced by cold light lamps and LEDÂ´s .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