hello ,

poke a hole in the bottom of the cup and cut out a circle about the same size as the size of the paper towel tube.Next, your can tear off a piece aluminum foil and roll it around the tube, taping it down at the ends.Invite you to place heart stickers on the tube or decorate it with markers.Fit the paper towel tube into the hole at the bottom of the paper cup, and reinforce it with some glue.Take turns placing the cup on a person's chest and listen through the tube.
