  • It's time to head outside and play!

  • And it's summer, so you know what that means: we can play in the sand!

  • Maybe you've had a chance to play in some sand, tooin your own yard, or at school,

  • or even at the beach.

  • If you have, you know it can be a lot of fun to play in!

  • Sometimes I like to let sand flow through my fingers, or have Squeaks bury my hands

  • or feet.

  • But one of the coolest things you can do with sand is build stuff.

  • [Squeaks squeaks]

  • Yes, Squeaks, like sandcastles!

  • But it can be tricky to build a sandcastle that doesn't just crumble away.

  • Big sand piles are fun too, but they're no castle!

  • So here are four tips to help you build an awesome sandcastle!

  • Step one: use plenty of water.

  • Water is the key to building a great sandcastle, because sand that's too dry doesn't stick

  • together at all!

  • And here's why: if you could look at sand closely — I mean, really closelyyou

  • would see that it's made of tiny pieces called grains.

  • If you try to build a sandcastle out of dry sand, the grains just fall apart.

  • There's nothing to hold them together.

  • But if you mix water in with the sand, then something really neat happens.

  • Little drops of waterso small that you can't see themsqueeze in between the

  • grains of sand.

  • The teeny water droplets stick to the grains of sand, and form what are kind of like little

  • bridges between the grains.

  • These bits of water act like glue to hold the grains of sand together.

  • If you don't use enough water, there won't be enough of these bridges, and the sand will

  • fall apart.

  • So make sure you mix plenty of water in with the sand that you're going to use to build

  • your sandcastle.

  • Step two: give your sand a wayand some timeto drain.

  • Draining the sand means making sure there's not too much water in it.

  • If it starts to look more like soup, that means there's too much water for those little

  • bridges to form, and the grains of sand won't stick together.

  • So you should let the extra water drain from the sand before you start on your castle.

  • That might mean using a tool with holes in it, so that the extra water can get out.

  • Or you might want to just let your sand sit for a few minutes before you get started.

  • Once the extra water is drained out of the sand, you're ready to move on to

  • Step number three: make the castle's base.

  • Every sturdy building, whether it's a skyscraper or a sandcastle, needs a sturdy base, or bottom.

  • If the bottom isn't strong enough to hold it up, it could crumble or tip over!

  • A good sandcastle base is made out of tightly packed sand.

  • So, if you're using a bucket or cup, make sure you press on the sand to pack it in tightly.

  • And if you don't have a bucket or cup, no problem!

  • Just make a pile of sand, and press on it as hard as you can.

  • Then, add more sand on top, and press again.

  • Do this over and over until you have a nice, big pile of sand that's tightly packed.

  • Step 4: use your imagination to make your castle!

  • Once you have a nice, sturdy base, you're ready to shape your castle!

  • You can use your hands and fingers to shape the walls.

  • Then, you're ready to add towers, seashells, or anything you can imagine!

  • Just make sure not to add too much sand on top of your base, or your castle might crumble.

  • And no matter what kind of castle you build, don't forget to have fun while you're doing

  • it!

  • I can't wait to keep working on my sandcastle and make it even more awesome!
