Children often love to play with musical instruments. One way to encourage your children in their interests is to help them make musical instruments of their own. Flutes take little time to make and are fun to play with afterward. They also make less noise than drums and tambourines, so they benefit both parents and children. You need few things to make homemade flutes; you can even recycle a few household items and work recycling into the project, too.
Lay a ruler along the tube and make a mark 2.5 inches from the end of the tube and a second mark .75 of an inch from the first mark. Connect the two marks to make a small rectangle .75 of an inch long and about .25 of an inch wide. This creates the dimensions for the mouthpiece.
Cut a circle of paper about an inch larger in diameter than the opening of the tube. Place the paper over the end closest to the mouthpiece. Glue the paper in place by folding the fringe of excess paper down over the outside of the tube.
