The Buckeye State offers numerous opportunities to peek behind the scenes of the manufacturing process.

In need of a new rainy-day activity or a creative idea for a day trip? There's no shortage of family-friendly factory tours in Central Ohio and beyond.

“People are becoming more conscious of learning about things made locally, and a factory tour is a great way to see that in action,” said Megumi Robinson, director of public relations for Experience Columbus, the city's convention and visitors' bureau.

From baseball bats to chocolate to recreational vehicles, you're sure to find something that appeals to all families—and budgets. We've assembled a roundup of some of the most popular kid-friendly tours in various corners of Ohio.

Children are required to stay with an adult at all times during the tour. Eye and hearing protection are provided, and guests must wear closed-toe shoes. Reservations are necessary only for groups of 10 or more. A small gift shop is on-site.

“It's a great atmosphere,” said Sharon Agriesti, office associate. “People of all ages enjoy tasting the different flavors, and you get to see how the popcorn is made in-house.” (Though guests don't visit the kitchen, they do watch a video showing the production process.)

When: 9 a.m. to 4 p.m. Mondays through Fridays.Reservations are required.

Many people don't know the country's only manufacturer of metal whistles is based in Columbus. The American Whistle Corp., founded in 1956, produces more than 1 million whistles each year. Visitors can learn how they're made during an hourlong tour.

“You can see the machinery used … and they can tailor their tour to an age group,” said Robinson of Experience Columbus. “Each participant gets their own whistle. It's a good idea for a birthday party, especially if you have kids and their parents going along.”

Tours require 15 or more people, but don't worry—the company will combine smaller groups as needed. There's also an on-site gift shop.

Anthony-Thomas Chocolates

1777 Arlingate Lane, Columbus; 877-226-3921

When: Drop-in tours take place from 9 a.m. to 3 p.m. Tuesdays and Thursdays. They also are available on Wednesdays from June to August.

Cost: Free for children 2 and younger, $1 for ages 3-18, $2 for adults. Customers get the ticket cost back via a voucher for the on-site retail store.

Anthony-Thomas Chocolates designed its factory, which opened in 1995, with tours in mind: A suspended, glass-enclosed catwalk allows guests to walk above the production area, which makes up to 30,000 pounds of candy per shift, and to see how the chocolate is made and packaged. Tour groups generally range from 12 to 30 people. The route is wheelchair-accessible. The 45-minute tour ends with a free buckeye. In the spring, watch for special Easter tours.

“It's not only fun, it's educational,” said Candi Trifelos, director of retail and marketing for the company, which was founded in 1952. “We have families that make it a point to come every summer.”

When: 10 a.m., noon or 2 p.m. Mondays through Fridays

Cost: Free for children 3 and younger, $3 for ages 4-18, $4 for seniors, $5 for adults

Thanks to modern laundry equipment, your children may not even know what a washboard is—let alone that it has dual uses. “It's still a pretty cool, functional product, whether you are doing laundry or playing music,” said factory manager Marissa Fickel.

Tour guests get to hear washboard music and learn about how the hand-assembled product is made. Columbus Washboard Co., in business since 1895, is the only remaining U.S. washboard manufacturer.

“A lot get sent overseas and to our servicemen and -women to do their laundry,” said Tammy Brown, public relations manager of TourismOhio. “There are countries outside of the U.S. that still don't have that technology to be in a place with washing machines and electric. They still use these washboards.”

Groups can take a self-guided tour, which lasts about 35 minutes, or make a reservation for six or more people. The factory, which also has a gift shop, is just under an hour's drive from Columbus.

phoenixbats.com/take-a-plant-tour.html

When: 1:30 p.m. Mondays and Fridays and 6:30 p.m. Wednesdays

Cost: $10

Phoenix Bats offers an hourlong tour that educates visitors about the history of the company, which was started in 1996, as well as the manufacturing process. Phoenix supplies bats to Major League Baseball players, but anyone can have their own custom bat created. See how a bat is made, cut and sanded, what types of finishes are used and more. You'll get a mini-bat at the end of the tour.

The company uses a wood-shaping machine that's one of only two in the world, and produces roughly 20,000 bats each year. Leftover sawdust from the bat-making process is given to a local farmer for animal bedding, said Christina Rutledge, customer relations specialist.

Reservations are not required for the regularly scheduled tours, but groups of 10 or more people should call ahead to schedule a time.

When guests arrive for a tour, they hop on a trolley, which runs every 15 to 30 minutes. Although visitors won't go in the kitchen, they'll see the receiving warehouse, lollipop-wrapping room, finished goods warehouse and more. Parties of 20 or more people can make an advance reservation. Spangler is roughly three hours from Columbus, in the northwest corner of the state.

Did you know that each one of the 700,000 leather footballs Wilson Sporting Goods makes annually comes from Ohio? It's been that way since 1955.

Wilson's factory in Ada, 90 minutes from Columbus, offers a one-hour tour that lets football fans see how the product is created. “You get to see how the footballs are hand-stitched,” said Brown of TourismOhio. “It's not something you think about. There are people lovingly crafting these things we see and use on a daily basis.”

Tours are limited to ages 8 and older, and closed-toed shoes are required. Protective eyewear is provided.
