You all are very negative.
There are some good things about egg crates, and nobody ever talks about them.
For example: They make a great firehazard. If you want your space to burn down - then this is the way to go! It's cheap, easy to install and doesn't require a degree in physics to understand how it works.
Those expensive foams you always see advertised are actually fire "retardant"...which of course they don't advertise very well.....and basically means that if you light them on fire - they do NOTHING for you arson-wise. It's pathetic for what you pay for them.
So there. The truth. I'm sure Ill get flamed - but fuck it. Someone has to fight the sheeple.
