Used them for a birthday party. Kids love something that they can create themselves so it was a huge hit.

So fun! We loved making these balls and giving them out as party favors for my 9 year old’s birthday party.

My science loving daughter gave these out at school for her birthday and they work fantastic! Super easy to do!! Just need to have a little patience to wait for them to set :)

I bought these for a gift bag for my grandson's 6th birthday party. The boys seemed to be excited when they saw it. Don't have any idea how it works.

Love these for party favors. They actually works.

As these kits were individually packaged, they worked great for birthday party favors. They were fun for kids to make.

Used as party favors kids loved them

Very cool project, gave them out for my son's 5th bday and everyone loved it.

The kids Loved making them very easy to do .

Kids absolutely had a blast making their own bouncy balls! I even made one too!!
