how can i make a LED light hula hoop? Answered

i am having a hard time finding small LED lights that will fit inside tubing. small ones that have a few individual little batteries that fit inside the hoop itself. it cannot be one big battery pack. the weight would be off and the pack would be awkward.

You can look at instructables for "joule thief" or "LED throwies" You can wire up a few LEDs with long thin wire-a resistor or two, thread them through the hoop and use a few coin cells taped in place. If necessary a AAA sized battery or two might not be too heavy to make it unbalanced. Cut the hula hoop and just tape over the joint to seal it. Good luck.
