Welcome back to the workshop. Today we’ve got an experiment
to see if we can make “magic sand.” That’s sand that you can pour into water
and it doesn’t get wet. There are commercially available versions
of this same idea but we want to know if we can make it ourselves. To experiment with this
we have a large bag of quartz sand and three different
versions of waterproofing that we’re going to try applying to
the surface of the grains of sand. We have a silicone-based spray,
this fabric Scotchgard, and the two-part NeverWet spray. All three of these products are
supposed to do a very good job of waterproofing different materials. So let’s apply some to
three different batches of sand and see which one gives us
the most magic. You can see I don’t have a very thick
layer of sand in each of these. That’s because I want to get really good
coverage with our waterproofing spray. If the sand is too deep in the trays it will have a really hard time getting
through and sticking to all of it. Now it’s time to apply each of our
water-coating sprays to the three batches of sand. First let’s label each pan with its
corresponding type of waterproofing so that we can keep track of
which one’s going on which. This is silicone,
so we’ll put SIL for silicone. SG for Scotchgard NW for never wet. All three of thesewaterproofing systems
have warnings on the cans that you should be careful not to breathe
too much of the fumes, so let’s take these outside and spray them down. First up is the silicone spray. You can see a slight change in color
as the spray coats the sand. It’s veery mild, though. Next up, the Scotchgard. And finally, the NeverWet.
Now this does come in a two- part system so we’ll have to
apply Step 1, let that dry for the appropriate amount of time,
and then apply Step 2. Now we’ve sprayed each of these batches
of sand with waterproof coating so we need to let them dry out a little bit. I kind of wanted to try using a heat gun
or putting them in the oven at low temperature to speed up the drying, but all of them contain warnings
about not letting them get near any sources of heat and sparks,
anything like that and so I think we just have to do it the
old-fashion way and let them dry out. Since we’re not actively spraying into
the oven it would probably be fine but, just in case, I don’t want to risk it. I don’t think Grant wants me to
blow up his oven. There we go. We’ve got
one side of our sand sprayed with each of our different
types of waterproofing and it’s mostly dry at this point.
So what I want to do is stir it up and then flatten it out again
and spray on a new coat to try and make sure that we have all of the
different edges of our sand nicely coated. That’s something.
Our first layer of NeverWet kind of makes the sand bond together into sheets. We’re just going to break that up. Turn it back into particles of sand. There we go. Now let’s add
new coatings to each of these. And I think what I’m going to do is spray
on a coat and then just sort of stir it up, spray on some more, stir it up and do a
few layers all at once to really try and get all of the coating spread
very evenly around the sand. There we go. We’ve got
all three of our sands coated in our different waterproofing materials.
Now let’s let them dry out completely and see which one has the most magic. The NeverWet, of course,
because it is a two-stage process, will need the second layer
applied in a little while. Let’s let this dry for 30 to 40 minutes,
then let’s do the same thing with the Step 2 of our NeverWet. At this point, all three batches of sand
with all three types of coatings have had the opportunity to dry overnight, so now
I think it’s time to see what happens if we pour them into water. It is interesting to see that
the different coatings have left slightly different textures on our sand. To test this sand out I’ve got a whole
bunch of water in our glass jar and we’re just going to try adding
spoonfuls of each different type of sand in here at a time and see what happens. To start out I think we’ll test the sand
coated in the NeverWet because I suspect that’s going to give us
the best hydrophobic results. So that mostly just looks like
a spoonful of sand, but the sand isn’t really getting permeated by the water. It’s just sort of there. Now let’s see what happens when I take
the spoon back out of the water. Instantly goes dry again.
Let’s do that again. Underwater Back to dry powder. Underwater; dry powder. Every time it does that
a little bit of sand falls off the spoon into the surface of the water,
just kind of floating there. What if I can gather back up? Nope, I just made more fall off. The pressure of the water is kind of
holding the sand on the spoon; it doesn’t really fall off. All right, I’m gonna lift the spoon
out of the water at this same angle. I think once it’s out of the water
all the dry sand will just fall right off. It fell off and then it’s floating.
It repels the water so much that none of the water can get in
or above it to make it sink. I’m just going to push it under and see what happens. There it goes. Just clumps together as
one piece down at the bottom of the water. Pull that out. Oh—back to powder immediately. This stuff really likes to float well because
it doesn’t like to go under the water. Let’s try more. It’s under the water,
but the part that’s still on the surface is still repelling the water and holding air
in it so much that it’s making it float. Let’s try and just get it to sink.
There it goes. Just this solid block of sand
holding itself together underwater. It just doesn’t want to mix
with the water at all. And it’s very buoyant because it has
so much air trapped inside it. That is some very neat
underwater sculpture-like things. In addition to the NeverWet
we did try using some Scotchgard and some silicone waterproofing spray and we got mixed results with both of them. Both of them made the sand
somewhat hydrophobic and we were able to pour the sand
down into the bowl and it would clump up
the way you would expect it to. But after a little bit of time
it did seem like the water was starting to soak in and get the sand wet. In the end of the silicone spray and the Scotchgard were somewhat effective, but the NeverWet worked much better. Now there is one more test that I wanted
to do to make our sand even more magical. This sand is sort of a white color
and it’s kind of boring. We want to try and find something
to make it really pop when you’re playing with it in the water. This is a new batch of sand
that’s not yet waterproof. I have this turquoise, alcohol-
based ink and my airbrush and I’m going to try and see if I can
color the sand before I waterproof it. All right. I had to turn the psi way down because the air was just
blowing the sand all over the place, but by holding it a fair way away I am able
to get some of that ink out onto the sand. It’s still blowing the sand around
a little bit, but not too badly. That’s one layer of sort of coating on there.
Let’s mix it up and add some more. We’re definitely getting some good color added. Just takes a while. Well, we haven’t coated every side of
every grain of sand on here but I think we do have a nice
turquoise color going. Let’s try waterproofing this and then see
how it looks in the water. There we go. Our colored sand is now coated.
Let’s let it dry out and then put it into some water. Let’s see if now we have some
brightly colored hydrophobic sand. That looks pretty cool. There we have it: An experiment
using three different types of sprays and some sands
to see which works best to make our magic water-resistant sand. I think we got the best results
using our NeverWet although, like I explained before,
I don’t like how it clumps up after the first stage. You really have to
go in and break it back up into the individual grains of sand
before you apply the second coat Using a little bit of alcohol ink
and an airbrush did a great job of dyeing our sand
a beautiful turquoise color. I did use the silicone spray on the
turquoise sand which worked fairly well. At this point I do kind of wish
I’d used the NeverWet as that is a little bit more hydrophobic. It repels the water a little bit better. If you want to make your
own version of this magic sand, I would recommend going with the NeverWet
and just give it a little bit of time really breaking it up into fine particles before you start adding on
the second coat. This stuff is pretty fun to play with. It
makes really cool formations under water. It’s really fun to pull it up out of the water
and watch the water just break off of it and leave the dry sand underneath. If your sand does get a little bit wet,
pull it out of the water, squeeze it off, let it dry off in a paper towel or on a tray. Once it’s dry it will be returned to
its water-repellent state and you can pour it back in again and watch it form those cool twisty,
swirly shapes under water. Once again, thank you to Squarespace
