Step 2Making the cap
This is one of the most dangerous parts of the whole project, so take extra care and get adult supervision.
Remove your green wax from the burner and let it cool for a minute or so. If a film covers the top, you waited a bit too long, but you can still use the wax.
While holding the light bulb with a thick glove or rag, carefully pour the melted wax into the bulb. Do this outside or over newspaper so nothing will get ruined from the wax. Stop pouring the wax when the bulb is filled 1 cm from the top. If you have a metal funnel, it would make this step a helluva lot easier. I didn't, so I did it the hard way.
Place the bulb in a cool, secure, and stable place in a vertical position. Don't place the bulb near plastic or flammable items, kids, or pets. Hot wax can cause 2nd to 3rd degree burns. I set mine near a table fan so it would cool a bit faster.
Let the wax dry, perhaps a day or so. It's better to wait too long than not long enough.
