Question

You want to build a sand castle on the seashore that will last two days. What two things should you consider?

Answer 1

Placement and shape/size

Explanation:

Placement: if the castle is to stay up for two days, you need to take into consideration the tide, and how far up on the seashore it will get. You need to know for a fact the ocean will not touch it, because if it does, chances are it will dig away at the foundation, making it topple over. You also need to make it in a place That little to no people will be there, so that they will not knock it over.

Shape/size: again, if it is to stay up for two days, you need to also consider the other weather than may occur. You need a good foundation that will not topple over. You need it tall enough that if some sand blows away, it will not matter. If it rains, you should have enough sand there that it would stay, and/or have something covering it, protecting it.

Answer 2

Answer: sand and water

Sand : The first and most important thing you need to know about sand is that you can't do a thing with it unless it's wet. Here's why: when you add water to grains of sand, the liquid forms "bridges" that connect the granules to one another. This is why damp sand sticks together, so you can shape and carve it.

Water : Use lots of water. Dry sand in its natural state is lazy stuff. It wants to lie down and spread out into all sorts of nooks and crannies. The good news is that as long as you keep gravity working for you, there is really no way to add too much water. Which brings us to our second rule.2 Let it drain. If you've ever tried to make the base of a sandcastle by filling a plastic bucket with wet sand and then trying to unmould it, you've seen how important this rule is. With no place for the excess water to drain off, the sand makes a sucking, sticking, vacuum seal with the plastic and it becomes difficult, if not impossible, to remove the bucket.This is why successful sand sculptors do not use plastic buckets or other closed moulds but build their shapes by stacking handfuls of wet sand or by tamping it down in a topless and bottomless form.
