Jennifer Garner dropped in on Instagram over the weekend to share a fun pool activity with her 16.3 million followers.

The 52-year-old actress — who shares three kids with ex-husband Ben Affleck — sported a black, one-piece, halterneck swimsuit as she was joined by who appeared to be her 12-year-old son Samuel.

‘If you have access to a pool, spoons and goggles — please borrow my recipe for a good time. Kid not required,’ she advised in the caption.

In a video clip she shared, ‘It’s the best game. We throw our spoons — three spoons each — and we start the stopwatch.’

The Alias alum explained further: ‘We each have to go and collect three spoons but in different parts and come back and turn off the stopwatch.’

‘We’d love to show it to you,’ the Hollywood fixture said before she threw one of the kitchen utensils into the water.

Her lighthearted reel was softly soundtracked by the song Mr. Blue Sky by the Electric Light Orchestra.

In addition to Samuel, Jennifer shares Violet, 18, and Fin, 15, with her former spouse, who is now married to Jennifer Lopez — with whom he seems to be estranged.

‘There’s strategy,’ she said at one point during the aquatic activity as she wore black goggles.

At another point in the snippet, the silver screen siren said, ‘I’ll go that way,’ before the tot said, ‘No, I’ll go that way.’

‘Oh my gosh, the course keeps getting harder and harder,’ Jennifer gleefully noted.

Then, checking the time on her iPhone stopwatch, Garner acknowledged to her son, ‘You’ve really set this up to be a tricky one. We have to go at the same time.’

Finally, she checked out the time, which read 00.29.32, and declared: ‘We’ve got a lot of work to do.’

It comes after Jennifer recently appeared on the Today show with her 86-year-old mother Patricia, in which they discussed her late father William Garner.

When host Hoda Kotb mentioned Jennifer’s April 1 Instagram tribute to her dad, the actress replied: ‘Oh yeah, I mean how lucky to grow up with parents like mine. I’ve always been aware of it, my sisters and I are… we’re always really aware.’

Jennifer praised her mom and shared her favorite things about her.

Garner seems to be enjoying her summer as Affleck and Lopez – seen here in January – spend theirs apart. Affleck has been in Los Angeles with his kids and Lopez has been in the Hamptons with her twins Max and Emme

‘I mean, I have a pretty special mom. So, my mom is not judgmental of people or of things or if things are happening to you.

‘She is just kind of gifted at giving to people and seeing what people need and just quietly taking care of them,’ she gushed as she held her mom’s hand.
