Be a sand artist
I know that it is not the same, but there is an online software to create your own sand picture. Its name is thisissand. Use the mouse to start and the sand begins to fall. To change the colour use the letter "C" in your keyboard, to erase what you have done use the letter "E", and with the arrows you will use the different colours you have selected before. Try, its funny!
And... this happened:
SAND ART everywhere in our classroom.
