I don’t like sand, it’s coarse, rough and gets in my science.


#3

Gasp! That suggests so many fun ideas, of which replacing sand with glitter is only the beginning


#4

I’m sure I would have been so much more engaged in middle school/high school science class if the lessons, or even videos, had been prepared this creatively.


#5

It has a high yield fun factor.


#6

Goggles suggested.


#7

Glitter is herpes for your house. I am still finding golden glitter in weird places a year later.


#8

You’re not alone. Scientists are suggesting glitter as we know it is as bad for the environment as plastic microbeads are


#9

Fake Christmas tree ‘leaves’/‘needles’ too. Almost time to put up the tree again and I’m still vacuuming up last year’s.

Anyway, on-topic - wouldn’t the sand from this be very uncomfortable in various cracks and crevices?


#10

would definitely recommend goggles


#11

Those balls rising out of the sand were pretty creepy.


#12

Great experiment and video, but personally I’d wear a very good mask.

Too much respirable crystalline silica and tremolite in that hot tub for me.


#13

You just took my post. When I saw the young boy go under and saw the silica mist I was horrified. This is extremely idiotic and although I don’t think Boingboing has realized what they are popularizing, it reminds me of an NPR piece that glorified coal rolling as a fun all American thing to do. Sheesh…

Billions of years from now, as the sun goes red giant, the Earth will have mixed feelings. Down side: Oceans boil away. Up side: Glitter finally burns away, too.


#15

“would definitely recommend goggles”

And bunghole sealant.


#16

Would this be a good all-over-body pumice stone?

Don’t stay in there too long!


#17

Can’t be worse than spending the day at the beach or going to some sand dunes :slight_smile: Where i grew up we had both though at least generally when you go to the beach you sometimes have access to showers before the ride home. Not so much with dunes.


#18

this guy needs to be the next science guy. some producer lock this guy up in a contract and get rich off of his earnings.


#19

In these days when so many people wastefully fill their families’ pools and hot tubs with water it’s good to see someone teaching their children good traditional Fremen values.


#20

Naturally, my impulse is to combine that machine with this one, and create impossibly huge objects.
