Best DIY Scuba Diver Costume for 5 Year Old

He wore solid black stretch pants, solid black long sleeve shirt with hoodie, solid black socks, and his swimming shoes.

We already had the scuba mask, scuba norkel, and scuba flippers from this past summer. They are the youth size scuba kit from our local store.

To make the air tanks, we painted two 2-liters the color green to match his scuba gear.  We painted the lids the black to represent a real scuba air tank. We used black duct tape to keep them together. We borrowed a pair of black suspenders from his sister to secure them on his back.  We reversed the suspenders. We clipped the 2 fasteners on the back onto the tape and the single fastener to the fron of his waist band. It worked great.  When it was dark outside, we put a green plastic glow stick and a LED light stick in each tank.  He glowed from a mile away.

To make the air regulator. We used tubing from an old cpap machine. We put the tubing thru the caps of the 2 liter and then around his neck. When it was dark outside, we put green glow sticks in the tubes and it really looked awesome.

To make the weighted belt.  We used and old guitar strap. We coverd 2 small ring boxes with aluminum foil. We attched the "weights" with velcro.
