English Heritage. I'm also here to give you some top tips. Tip number one: with dry sand

you can't make anything. Sand has to be wet, and then you can make beautiful things. Tip

number two: to make a castle you need to have a strong foundation so for that I'm going

to build a volcano. Ta-da! When you've got your volcano then what you need to do is just

get a bucket of water and pour the water into it. Because you've made this nice little rim

the water's not going to go down the sides. Then all we do is use your fingers to press

on it like you're playing the piano. When you're doing that it actually make the sand

go really really hard. And it will go so hard that you can now build your castle on top

of it. Tip number three is to use your hands to compact and carve the sand. Get one hand

nice and still and then bring the sand up and pat it against the other hand and that

sand's going to go nice and hard. Tip number four is to use a ruler and and knife to do

the cutting and the details on your sand sculpture but make sure

they're made of wood. So now we've got our motte and we've got our bailey with our keep

on the top, we've even got a little village but we've got no walls to defend it so tip

number give is to build walls. You push the sand together and pinch down with your thumb.

And then just take the sand and give it a little finger tap and when it stops being

like jelly then you stop tapping and you'll start to make these towers. It's so nice and

gooey, look at that! So here we have our sandcastle and it's got its walls but it's got nothing

to hide behind for the soldiers to protect themselves so tip number seven is to make

crenellations. For this you're going to need a wooden float and plenty of muddy sand. So

get your muddy sand and put it onto your wooden float and give it a little finger tap again

to vibrate the sand and then if it's too muddy just add a little bit of dry sand and keep

going until it turns into a hard piece of sand. You'll then take your ruler and you

make a little bit of a chocolate bar. When you've got your chocolate bar you need to

cut it up into little blocks then gently take them over and put them onto your towers. Okay

so we have our castle and we have our moat but we have no way of getting out so tip number

eight is to make a drawbridge. So what you do is just make your hand nice and big like

this and have it raised a little bit and then just pat the sand over it like so. And then

I'm just going to take my hand down and make it smaller and hopefully I'll be able to take

my hand out and there will be a little hole left there. And then you can use your ruler

just to cut the bridge. And those are our tips for making a lovely sandcastle.
