We want to make sure to use a lot of water
because we want to make sure that the sand isn’t going to fall apart and crumble. It’s
a good idea to use a spray bottle throughout your sandcastle building because if the sand
dries out too much, for example here, it’s not going to be able to pack and you’re going
to have a hard time keeping all of your pieces together. So, the best thing to do is use
your bucket or your spray bottle to get sand that is packable into different shapes. As
the day goes on, the sand will begin to dry. Sand like this is no good for building a sandcastle.
You need to keep lots of water around to continue to pack the sand tight.
