Step 1: Materials
1. Ball bearings: id say anything atleast half inch in diameter or larger will be what you want. Bought mine awhile ago want to say they are 1.25 in. Also adds weight to prevent tipping.
2. Alligator clips, or back in them hippie days (roach clips). Probably don't want to go to big here crush what your soldering. I also used the clips off the ends of a cheap battery tester. Note they have pinching power. So i used the rubber gips off the handles to put on the mouth. Grip and a bit of padding. Nice to the colors can distinguish between pos and neg for your project.
3.hot glue gun and hot glue sticks. ♨ skin burn alert. Stop, drop, and roll that glue off your fingers quick. Ive noticed depending on the amount. Usually rubbing/rolling glue in a ball after skin contact minimizes burn. But always keep a deal of water near by. Trust me there. Plus im inpatient. So it helps cool glue super fast.
4. Old AAA or AA batteries if your of the wealthy descent $10 rolls of quarters hehe kidding. Would work fantastic tho. And be worth like $65.
Neat lil trick for giggles...... Normally there is abother word in front of giggles.... Take a darker colored marker and color glue sticks. Leaves a faint color after completely cooling. Doesn't ruin glue gun either.
Ok i lied on the blinking and missing. More of a eyes closed for a good snooze. Would be more like it.
Step 2: Whatcha Gluing There
But now glue one battery to each bearing to where they make the tip of what is gonna be a pyramid. Once they set. I put a few blots of glue on each battery and get the third bearing on place. Then smother with glue gravy. Youll note that without cold water nearby there will be quite a bit of waiting time. So i speed every step up that way. You do run a risk of water getting between bearing and glue. Causing it to fall out. So be careful there. Once the bottom of your pyramid is set. Well you glue some more of course ;).
