помогите составить предложения со словами Be over (кончаться), celebration

The celebration was nearly over when the guests were offered tea. But it turned out that host had run out of it as the company had been having tea the whole day through. To put things in order the host used all available cans of coffee. Standing upright among the guests he offered them to compete who would try and sell out the greatest number of cans. The competition took place in the garden and became a great adventure demonstrating the crowd's creativity in trying to sell the greatest quantity of can though that was not exactly what the host had had initially in mind.
