Do you remember a toy that was a capsule with a weight inside?

Included in a boxlot of miniatures and toys was a plastic capsule (pill type) with a heavy ball rolling around in it. I have a vague memory of something like this coming in pairs in a little bag with a header. But cannot, for the life of me, remember what they did.

Do you remember?

 

Mexican jumping beans.

I think they were also used as bombs in WWII hand held games so as to get them in the targeted holes.

 

I thought about that but the ones I had as a child had an insect in a cocoon. I didn't remember they sold fake ones too.

Thanks!

 

Mexican jumping beans was my first thought also...ahhh, memories...

 

I have/had several (circa 1960). They are packed up somewhere, or I'd post a photo.
Some had little faces painted on, others did not; and some came with a molded ramp or tray, about 6" long and as wide as the width of the capsule.
The capsule could roll end-over-end down the tray when it was tilted; then one would tilt it the other way and it would roll back. It was sized so that at either end, the capsule ended in an upright position. For the amusement of children. Not sure what the name of the toy was.

Here's a current version:

Well, I'll be darned.
Just when I think I'm a worldly woman who has seen it all...

 

I remembered them, but couldn't recall the name. I also had the jumping beans.

 

Haven't found any photos of old ones with a track though....

 

As opposed to real jumping beans, frijoles saltarines:

Thank you for the info and the memory refresher!
