Summer ushers in many opportunities for kids to run and play — but sometimes the default is gaming on the couch if an engaged adult doesn’t intervene.

How about you, Grandma or Grandpa? Here are three chances for active, extra-fun summer playtime you can enjoy together, whether you play too or are merely a spectator, chaperone or chauffeur:

Ooze out with serious slime at the Sloomoo Institute

By appointment, 10 a.m.-6 p.m. weekdays, 9 a.m.-8 p.m., Saturdays, 9 a.m.-6 p.m. Sundays, 1 and under free, general admission $39, enhanced $69, PLAY: Sloomoo Institute, 3637 Peachtree Road NE, Suite D, Atlanta.

Maybe your own childhood did not include dreams of getting slimed, but your grandkids will probably look forward to the experience.

General admission grants access to a lab where you concoct 8 oz. of slime from different colors, textures and scents and various augmented reality experiences that take about 60-90 minutes. You’ll traipse 350 gallons of slime, for example, or see how you’d look as a slime creature in the Sloomoo mirrors.

Those who don’t gross out easily may want to pay for the enhanced experience where you’ll get vast quantities of the goo dropped on you from above. Do not, repeat not, wear school, church or date clothes for this.

The venue is designed for those ages 5 and up and offers a military discount.

Happily, anyone can skip the sliming and still hang with your party, but aren’t you curious?

Two-for-one mini-golf Thursdays at the Fringe

10 a.m.-10 p.m. Thursday, June 1, seniors 55+ and kids 3-12, $6, ages 13-54, $9, The Fringe Miniature Golf, 5100 Commerce Pkwy, Roswell.

Celebrate the end of school and the start of an active summer with this Thursday discount. Buy tickets for one course and play the second one for free. Don’t forget to show the littles ones and tweens how to keep score.

Enter the Aurora Cineplex, an affiliate business, to pay fees and get sized for putters.

Big Bounce and Slide Festival at Cumming Fairgrounds

June 2-3, 10 a.m.-9 p.m. Friday-Saturday, June 2-3, 12-7 p.m. Sunday, June 4, $30 general admission for anyone 2 or older; non-rider passes starting $15, a family four-pack $75, Cumming Fairgrounds, 235 Castleberry Road, Cumming.

The kids will sleep soundly the night after this adventure!

One ticket includes unlimited all-day rides, including mechanical rides, water slides up to 35 feet tall, bounce houses and obstacle courses, and a giant foam pit. Don’t forget to pause for free character photos alongside kiddie celebs like Elsa and Spiderman.

Plan to arrive before 4:30 p.m. for face painting. Bring extra money for the food trucks, too.

One nice touch: You can pay less if you just want to watch the slides and bouncing apparatus without participating yourself. But even if you don’t jump and slide, odds are you’ll sleep well after this exhaustive day of play, too.
