How to make a boat float key chain! (Maybe later I'll tell you how to make a McDonald's Coke, but start with this) You may have seen these, they are flotation devices incase you drop your keys in the water, just about every set of boat keys I’ve seen on the lake local to me has one already, new boats are likely sold with one, but those aren’t custom! Materials: 1. Memory foam (the kind you can mush to tiny size and it goes right back to it’s shape unobstructed like the giant #1 finger you get at the ball park). 2. Small clasping ball chain (like many advertisement key chains or other small promotional freebee type of objects may). 3. Liquid black tape (my local True Value hardware store carries this stuff in the electrician isle). 4. Craft Paints (hardware store again, many department stores like Target have suitable paints, and washables are okay too if using the clear Plasti Dip as the final coat). 5. Plasti Dip (a product by brand name that the hardware store carries which comes in a variety of solid colors, but I am using a clear one in spray form so I may see paint under it rather then painting over it). Tools: Disposable gloves and eye guard wear for safety. A scissors and last but not least a drying canvas (construction paper and a ventilated area not disrupted will do, like a crafts bench). Step 0; “read the labels,” you must read the labels of the products you buy if not familiar especially when adapting to instructions from consumers where products are used not as intended, that is why this is step zero, it should already be done as a consumer concern before purchase. Step 1; cut your keychain out of the memory foam using a scissors, more often then not I have seen them an elliptical oval shape and half an inch thick, you’ll want to also cut a hole for the chain part to go clear through the shape, be sure to have a nice amount of volume, nothing too thin. Step 2; coat the foam with liquid black tape being sure to cover the entire surface area, one coat will not be enough, so after the first coat is dry, put on another whole coat of liquid black tape, three if your really trying to make things smooth, I only did two. I tried applying Plasti Dip directly and ran right through the porous foam like water does, so it wasn’t suitable alone. Step 3; after the liquid black tape is dry, paint it! This is sort of like an Easter egg of fun! Also because this step is not the last, even washable paints will be protected from the final layers. I suspect you may use anything you like to decorate it, like glitter and things of that nature (if you’re the clear Plasti Dip of course). Step 4; coat the whole object yet again thoroughly with Plasti Dip. Apply at least two coats, waiting for it to dry for at least 30 minutes in between coats. This makes it durably protected to whatever illustration you may have put on it. I’ve seen free boat key chains often that have an advertisement on them like the dealership which sold the boat. I personally went with what I would name my pontoon boat if I had one. Step 5; put the ball chain through the hole you’ve cut for it and enjoy an awesome custom boat float key chain! I was crafting scale size pontoons when I stumbled upon this, so I made mine match the colors of my model pontoons and called my boat “Endo.” The finished key chain almost exactly like real ones, but is different I assume, it flexes the same staying squeezable and is unsinkable when the foam is completely covered correctly.
