"She showed them and let them realize their potential, that they could do something like this, that it wasn't impossible to touch other people's lives," Liolios said.

From the free-will donations of people who stopped in that day, the students raised $258.01 to support the missions.

"I think it was amazing that people would take a 10-dollar bill or a 20-dollar bill out of their pocket and put it in the (donation) box," Liolios said.

The message of faith in action even reached the local firehouse, when a fire truck stopped so firemen could share some lemonade and speak with the students.

Liolios said all the students involved played a part. Some researched how even a small amount of money could help people through the missions, others made posters to promote the event, and stills others contributed supplies.

"Some brought water, some brought the lemonade mix, some brought the coolers to keep it cold, and one brought a cashbox. They all contributed in some way to make this happen," she said.

"I said to them, you made a difference in other people's lives ... people that they weren't ever going to meet. I just feel that they just wanted to make a difference. They wanted to put their faith in action. It was really important to them," Liolios said.

The occasion that inspired the students' lemonade stand was an Aug. 1 visit by the director of the Pontifical Mission Societies in Jinja, Uganda, Father Alex Okello and the director of programs and development at the Boston office, Maureen Crowley Heil.

Father Okello and Heil talked with students about the Missionary Childhood Association, known until recently as the Holy Childhood Association, and its work of "children helping children" by supporting the missions in countries like Uganda.

During the visit the children also prayed the World Mission Rosary. Inaugurated in 1951 by Archbishop Fulton J. Sheen, the World Mission Rosary promotes prayer in unity with the world for the poor and vulnerable.

Heil said when the time came to report the students' event on social media, she made sure to note the exact amount raised was $258.01, because every penny counts in missionary work.

"That one penny was somebody's sacrifice, and it may have been the only penny in their pocket, so you never want to just round it off. That .01 is important," said Heil.
