EXTEND 3:  Now that we are creating a random speed every time we create food, let's use that speed!
	In GRAPHICS, from Set y Speed  indented inside the interval event. Change sprite  to food . This assigns the .set_y_speed()  command to the food  we just created! In .set_y_speed() , change 5  to rand_drop . The food now drops at a randomly picked speed. 
 Run  your game. Now the food drops at different speeds each time!
