A red tee, a whistle, and a rescue buoy made from a pool-noodle ring. An everyday hero. Twenty minutes, easy: a red t-shirt, a plastic whistle on a lanyard, and a pool noodle. The whistle should actually work; silent whistles disappoint children.

Materials

Red t-shirt, 1 (own, or buy: thrift store)
Plastic whistle on a lanyard, 1 (buy: dollar store or party store)
Pool noodle, 1 (buy: dollar store)
White duct tape, 1 roll (buy: dollar store)
Red shorts or swim trunks, 1 pair (own)
White face paint stick for the nose stripe, 1 (buy: craft store)
Scissors, 1 pair

Steps

Cut the pool noodle.
Curve it into a ring.
Tape the ends together with the white duct tape.
An adult should do the cutting: pool noodles need firm pressure.
Wrap 4 white tape bands evenly around the ring.
Safety: The whistle is a photo prop the parent holds and brings out for pictures, not a blow-all-night toy.
Safety: The buoy is a costume prop, not a flotation device. Keep the lanyard short so it cannot catch on anything.
Wear the red tee and shorts.
Carry the buoy over one shoulder.
The parent keeps the whistle and hands it over for photos.
Dab the white face paint stripe across the nose.
Optional pro finish: write LIFEGUARD across the back of the tee with white tape letters.

Common questions

How do you make the pool noodle ring stay round?

Cut the noodle ends at an angle so they meet in a clean joint, then wrap the joint with 3 layers of duct tape. The tape joint is stronger than the foam.

Is a real whistle too loud for a kid costume?

One toot at a time is the rule. Party-store whistles are plenty loud; skip the metal coach whistles.
