Hot, hot, hot!
Here is a quick way to keep stay cool with a style.
We will need:
✔ Styrofoam box
✔ Fan - more powerful, better. We used USB fan, but 12v fan would do a better job
✔ Glass bottle and bottle cutter to make a tube (We used Ephrem's Bottle Cutter)
Or you can use a plastic tube if you want. Glass looks cool :)
✔ 2 diodes, battery holder with batteries, switch
✔ Other: glue, cables, plastic sleeve, black acrylic paint, painter tape, etc.
First of all, we covered the painting area with painters tape, then
we painted one of the sides black.
Acrylic paint is great for this job.
