Goldie Hawnisn’t afraid to get into the muck of things for a good cause!

The Oscar winner, 76, shared a sweet video clip toher Instagramin which she sat with her granddaughtersRani Rose Hudson FujikawaandRio Hudson, as they played with Sloomoo Institute X MindUp’s “Slime for your Mind.”

Sloomoo Institute’shand-crafted, colorful and scented slime is akin to Play-Doh and is touted as “a celebration of sensory play” that can promote ASMR (autonomous sensory meridian response).

The experiential slime museum in New York has teamed up with Hawn’smental health organization MindUpto create a special version of the slime geared toward reducing stress in children.

In the clip, Hawn sits with Rio, her sonOliver Hudson’s 8-year-old daughter; and Rani, her daughterKate Hudson’s 3-year-old little girl.

The trio play with the stretchy, stringy substance, which also includes a clay slime “brain” in the form of MindUp’s logo.

Rani remarks in the snippet that the slime “smells so good,” asking her grandma to smell it.

The girls stretch the slimy substance into long strands, with Rani extending it all the way over her cousin’s shoulder.

At the end of the video, Hawn reveals a beautiful “cake of slimefulness” made from the Sloomoo goo.

Hawn, who was named one of PEOPLE’s Women Changing the World for the non-profit program, opened up about how her kids — Kate, 43, Oliver, 45, andWyatt Russell, 35 — have implemented some of her own parenting techniques.

“My children are really great with their children,” Hawntold PEOPLE in March. “They’ve taken MindUP principles and offered them to their kids, and they’re doing great.”

“So that’s the way it works. As a parent, you basically raise your children to raise their children appropriately as well. So that’s that domino effect,” she added. “And as parents, we have a tremendous responsibility.”

Hawn foundedMindUpin 2003 while on a break from acting that lasted 15 years. The organization provides curriculums for kids, parents and schools focusing on the mental health and “brain fitness” of children.

She said that though she wasn’t able to implement those skills in her own children, she’s hoping to be a vocal advocate for parents to teach their kids about mindfulness and mental health care.

In addition to Rani and Rio, Hawn is grandmother to Kate’s other kidsRyder Robinson, 18 andBingham Hawn Bellamy, 10; Oliver’s other childrenBodhi Hawn Hudson, 12, andWilder Brooks Hudson, 14; andWyatt’s son, Buddy Prine Russell, whom he welcomed last year.
