The Mad Scientist birthday was a complete hit. My son had a great time and told me over and over how happy he was. Total success, I say. Here are the dirty details in case anyone out there is in need of some ideas for a super fun kids’ party.
I used a picture of my son [from Christmas morning when he opened his official lab coat and immediately started laughing manically] and used Picnik to adjust the colors and add text. I wanted it to look like a magazine cover, so I added various “articles” and of course the featured “Scientist of the Year” as my son.
For the table centerpiece, I just filled various sized Mason jars and clear glass vases, all already on hand, with water and food coloring, water and vegetable oil (and salt, which made for a super cool lava lamp effect for about 20 seconds), and water and dry ice. Some of the jars also had small plastic snakes floating inside
I also sprinkled the table with tiny cut out warning signs
Next up was Oobleck. It’s cornstarch and water slime stuff. The instructions for it are at the end of the post, along with the rocks.
Super easy, really cool and cleans up very easily. Thankfully my older sister, who is an elementary school teacher, was in attendance and kind of took over this part for me, fully explaining the science behind it all and making sure everyone had the right consistency of slime.

|Baking Soda Rocks||Oobleck|
|Make a paste of baking soda and water. |
The paste needs to be pretty thick, so that it can be formed into a ball and keep it’s shape. I just added water slowly, testing by pinching off some and pressing to see if it would stick together, until I got to where I wanted it to be.
Get some small toys.
Place one small toy in the middle of a baking soda patty
And mold the patty around the toy, enclosing it completely.
So now it looks like a small snow ball
Place on ungreased cookie sheet
Bake at 200 degrees F. for about three hours.
Fill a large container with vinegar and add the baking soda rocks a few at a time. Everything will start to bubble and fizz
Use spoons, tongs, whatever, to roll your rocks around and help break them up
Soon the rock will fully dissolve, in a sea of foam and fizz, and your toy will appear!
|We premeasured one cup of cornstarch into a container for every guest, labeling with their names and dates ( my little sister got the chemical labels from the vet office where she works and the jars are from Oriental Trading) |
When the time came, each child was called up individually and we added 1/2 cup water
and food coloring of their choice
Then they took their jars back to the table and mixed well with spoons. Some jars needed more cornstarch added after we started stirring.
The resulting “oobleck” (no idea where the name comes from) is a cornstarch suspension, neither a liquid nor solid. The more the kids play with it with their hands, the better the consistency. But it’s basically a slime.
*Leftover baking soda paste, and the vinegar/soda mix from dissolving the rocks, makes great household cleaner. DON’T dispose of the baking soda/vinegar down your drains. Trust me on this. Three years ago we paid big$$$ in plumbing bills to clean out the mess I made doing just that.*
