I think that you are on the right track using the bulbs from a couple=20 of really-inexpensive series-string Christmas Light sets. These=20 bulbs are usually around 3V or so (divide the line voltage by the=20 number of bulbs) and they are all really easy to remove from the=20 plastic base. Just straighten the folded-over bare leads and pull=20 the plastic base off. That will leave you with bare leads almost a full 3/4 inch=20 long. Easy enough to work with. dwayne At 12:00 PM 9/18/2015, Denny Esterline wrote: >So, I have opportunity to reach about two dozen cub scouts about 6-9 years >old.
