For each scuba tank you will need-
2-clean and dry plastic 2 liter soda bottles or juice bottles
Duct tape (colored if you are feeling really artsy)
Xacto knife, sharp scissors
Material scraps cut or torn in about two inch strips or wide ribbon
This craft is for your child to use but for ADULTS ONLY to create. Tape the two bottles together like you see in the photo. I go around the bottles twice to secure them tightly. Tape around the bottles at the top and bottom. Next, cut two slits on each bottle at the top and bottom about three inches apart from each other. Cut the slits into a small rectangular 'button hole'. The photo gives a pretty good idea where to make the slits (it's not for a grade so it's okay). Put a safety pin on the end of the material/ribbon and drop down through one of the slits and pull through the second slit. Repeat for the other side. Have your child try on the scuba tank to get a good fit. The ribbon should create a strap that fits but is loose enough for a child to take on and off on their own. Tie a knot securely in the material/ribbon. Pull the ribbon so the knot is on the inside of the tank.
After the adult portion of the craft is finished, your child may want to decorate and personalize the scuba tank. Put shredded paper, tissue paper, or old gift bag stuffing inside the two bottles and put the bottle cap back on and super glue (an adult job). Use sharpie markers to color and get out all those stickers from the office supply store and have at it!
