Bucket and spade found on the beach

Q: When I went on the beach, I found a bucket and spade (which the children play with). The items were lying around close to the sea. The water of the sea was very close about to take away the items. I took the bucket and spade assuming it would have washed away in the sea if I hadn't taken it. Is it permissible for me to give it to my children to play with? In the above situation if the answer is no then what should I do with the items?

Q:

1. I have heard that all utensils must be covered at night as sickness or evil can come down. Is this true? If things like the cap of a shampoo bottle is left open by mistake overnight, can it be used?

2. Can the crumbs that collect on the table cloth be dusted down the sink if one does not have access to a garden?
