Class Time Directions
To create shoulder straps for your scuba tanks, first
place the foam panel in front of you so it is oriented
vertically. Then take one end of the black cord, thread
it down through the bottom left hole, up through the
top left hole, down through the top right hole, and
up through the bottom right hole. Then tie the ends
Now adjust the “straps” so the knot is located between
the bottom holes, and the right and left loops are about
the same size.
Try on the panel to see how it fits. If it’s too loose,
adjust the knot to make the loops (straps) smaller.
Place the 2 bottles side-by-side and carefully tape them
together with black masking tape. Two bands of tape
across and around the middle should be enough.
With the 2 bottles taped together and laying in front
of you, place the foam panel on top of the bottles and
position it so it is even on each side. Then attach it to
the bottles with duct tape. Now your scuba tanks are
ready to wear!
Possible color choices for the spray paint can include
black, silver, green, blue, yellow, or even hot pink.
If desired, add an air hose using ½-in. black corrugated
plastic tubing (available at hardware stores) and black
