Let’s see how we can make a French horn. We’ll need:

• one and a half meter of corrugated pipe,
• a funnel,
• tape or wire,
• a balloon,
• a party horn

Cut 4 pieces of tape. Take the pipe and loop it around. Secure the pipe with tape or wire. Then put the funnel into the pipe. Cut the balloon.  Remove the paper from the party horn. On the other end of the pipe put the narrow part of the balloon, then the party horn into the pipe. Now just put your lungs to work and blow the horn! Enjoy.
