Here's a fun way to spend time at the beach - build a sand castle. You don't need to be a professional, and you don't need special tools.
I built the Dinosaur sand castle in the photo in less then an hour and with very limited tools. Here's how:
First, find a nice flat area, out of beach traffic and close enough to the water so the sand is damp, not dry.
You can use your hands, or a small sand shovel to pile up a mound of damp sand. Make sure you pat it down so it's good and firm and stays together. Once you have a nice firm pile, smooth it out to form the body and back.
For the neck, get some pretty damp sand and carefully stack it up at front of body, bit by bit, patting it down as you add length to it. Don't go too high or it will topple over. For the head, get some pretty wet sand and form an oval shape in your hands, packing it firmly. Once you have the desired shape, carefully place on the top of your neck and smooth out the seams with your fingers. Adding wet sand if you need to, to act like glue.
For the tail, just add damp sand to the back end of the body. The legs can be carved out of the sides of the body, or you can add more sand to the body.
The spines were a bit tricky. I took small amounts of wet sand and formed them in my hands, then, very carefully placed them along the head, neck, back and tail. Smooth the seams with your fingers.
I added an eye by inserting a straw carefully into both sides of the head to form a socket.
That's it! In no time at all I had dozens of kids came over to admire my sand dinosaur.
