Blobs in a bottle...not quite...

The girls decided they wanted to try the blobs in a bottle experiment found on Science Bob's website.  They were supposed to look like this.  But ours didn't quite turn out that way....

We started out with these suplies:

The girls  poured everything into their bottles...

The loved how the water and oil immediately seperate!

We added the food coloring, and finally dropped in the fizzy tablets.

We saw reaction (You can see the white fuzzy looking spots on the surface inside the bottles) but we never saw colored blobs floating around. No matter what we tried.  We went back to the intructions. We used a different size bottle that Science Bob.  We used knock off alka seltzer and we used equal parts of water and oil because someone didn't have enough oil in the house to fill these bottles. I am sure any one of these things could have given us scewed results.  Either way, the kids still loved this project and I agreed to try it again, once we saved up the right supplies.

  1. What a fun little project! I'm going to have to try that out with my son when he gets a little older. :)
