Halloween LED Jellyfish Costume

Step 2LED rope necklaces

LED rope necklaces
These are the LED rope light necklaces. They are the kind that street vendors sell to kids at bonfire parties or street festivals (mardi gras?) for a couple of quid (3-5 USD). I guess there are many kinds, but the kind I found run of 3 x 1.5V button batteries, and are controlled by an electronic push button on/off switch.

Super cool intructable...I got sucked in because being a jellyfish would be great...but now would like to know if these neckaces coul dbe used for another project...LED hula hoop? To do this, my question would be, "Do you think the necklaces could be strung end to end and still work?" Thank you in advance.
