islands & coastline cities only (Operculum needed)

[Georgia Richards <garlic@MIND.NET>]

This group has done such a wonderful job on my most knotty problems that I=
 have another one for you.=20

 When I was in grade school we used to look for "vinegar walkers" in the=
 sand at the beach. We would take them home and put them in a jar or glass=
 of vinegar.  They would move around and make bubbles and slowly dissolve. I=
 remembered this while trying to come up with "different" projects,=
 discussions, and demonstrations for a 4th/5th grade class that will be=
 taking a trip to the coast. Now all I need is the operculums because that=
 is what they were(are). Can they still be found in the sand at the beach?=
 Do children in Hawaii (and other coastal places) still do this? If memory=
 serves, the ones we used are round or almost so and less than 1/2" across,=
 and of course flat on one side and convex on the other.  Sometimes they=
 were pretty pastel colors but most of the time they were some shade of=
 white. I would be glad to pay postage, time and all those things if someone=
 can find a few(because knowing these kids they will want me to do it again,=
 and again) and send them to me. I tried to do it with a small shell but=
 they are either too heavy or they turn upside down and refuse to move any=
 more.
