Blanket that you can draw light on

-

I was at a festival a few years back and I came across this dude who was laying on top of a glow in the dark blanket, pretty cool. But what made this blanket so amazing was that you were able to draw on the blanket with a laser pointer, so whatever you drew with the laser stayed on the blanket for a few minutes.

I have been trying to find this online but to no avail. Has anyone ever seen one of these? Do you know what this type of blanket is called, so I can buy it for festival season?

Etymotic Foam vs. Custom Earplugs

-
I'm trying to decide if custom earplugs are worth it for me... So I've been to concerts in the past, and I typically use Etymotic ER20XS earplugs with foam tips. I usually try to be close to the front (and usually end up off to the side), so maybe the sound would be different if I go further back and toward the center, but I find that with the foam tips, the sound ends up super bassy and the vocals become a little hard to understand. Is that a product of where I'm standing in relation to the speakers, or is that just the nature of foam tips? Could I expect to see a difference with custom earplugs? Comfort isn't an issue at all right now, I'm just curious if it would sound "better." submitted by /u/qadrty [link] [comments] source https://www.reddit.com/r/festivals/comments/puvmmy/etymotic_foam_vs_custom_earplugs/
