Man Vaps are awsome if you use them the right way and at the right time. I made one out of a lightbulb acording to the same website he reffered to, waytoomany.com. However, to be extra safe, i recomend filling the bulb with water and a little soap and a rinsing it many times. Then let it sit in the sun and dry out. (dont put heat directly on it to dry it faster. You will crack the bulb.) if you watched the whole video on the early mentioned website, youd see that there was two holes in the cap on the light bulb, one for sucking and one for air to come in.

My experience from using them is that you use a very small amount of weed and get very high. I was able to get high on 6 ot 7 different occasions with only 1 gram of merch. i think i way of been burning them the weed a little too much by holding the flame close, but i was still able to get just as high.

The light bulb vape is a cheap way to conserve weed. But it seems like its better to use for a solo high. If your with a group of friends, and they're used to smoking therw way, they probaly will think its dumb and a waste of time before they even try it. Just make one and try it out a few times and see if you like it.
