25 points me i have to make a thermos in science class using a styrofoam cup, cottonballs, and tinfoil. it has to keep water cold for as long as possible. what is the best way to make a thermos out of this stuff to keep it cold? tape cottonballs around the cup and put tinfoil on the outside? i have no idea me . : )

Line the outside of the cup with the tinfoil. Then put the cotton balls inside. Finally, line the cotton balls with the tinfoil and smush it all together.

so tape the tin foil on the inside of the cup, and out the cotton balls around the top. foil keeps things cold, so you will want it inside the cup
