Okay, so we didn’t quite make balls of fire—maybe “Great Rings of Smoke” would be more accurate.
During our previous meeting we investigated the nature of sound waves. One of the things we briefly discussed was what these vibrations in the air might look like if we could actually see them. This time out we tried to find a way to do something close to that.
In May 2010 the Explorers celebrated their annual pop bottle geyser festival.
This activity takes advantage of a phenomenon known as “nucleation,” in which bubbles form explosively in soda when given a suitable surface to latch onto. And when we say explosively, we MEAN explosively, as those club members who had not experienced this before found out for themselves.
On a chilly and windy morning in May 2010, the Explorers visited Clifton Gorge State Nature Preserve.
The group hiked first along the rim of the gorge, then descended to walk along the Little Miami River. After a stop to investigate some “slump block caves,” the group continued to a bridge across the river. Here the trail leaves the state nature preserve and enters John Bryan State Park. This was the turn-around point for this day’s hike.
