play with sand for money

Making sandcastles are fun, whatever your age. So if you have a modicum of talent, go down to your local beach, create some masterpiece out of the sand and put your hat in front and look pleadingly for donations. Being talented helps, like the people here. Just using your basic bucket will not make much cash. Also ensure that you are making your sculpture near the promenade where people will pass in the evenings and throw their small change. Putting it 1 metre from the sea is going to be shortlived.

You do not even have to live near the beach. The last time I was on the South Bank of the Thames, two people had the same idea as me, and were creating their masterpieces at the shore edge about 300m past County Hall.
