Trying again even in the presence of failure was the lesson of the day during a program at the Hastings Public Library Tuesday.
Dan Glomski of the Edgerton Explorit Center in Aurora gave two science-themed programs at the library as part of this year's summer reading program with the theme "Fizz, boom, read."
"Thomas Edison has one of my favorite sayings in science," Glomski said to a group of junior high students.
Edison was trying to invent the light bulb and tried dozens of times but continued to not have the results he was looking for.
"But he said, 'I've not failed. I've only found 10,000 ways that won't work,' " Glomski said.
Eventually, he did invent the light bulb. However, Edison had to struggle before he could find success.
That was the same situation during Glomski's PSI program Tuesday as he attempted to get his Ping-Pong cannon to work.
The concept was that he had a long piece of PVC pipe with a Ping-Pong ball inside. Tin foil covering both ends was held in place with more PVC pipe.
