Jenn Nielson, the chemistry whiz
Jenn is an extremely entertaining teacher
Mixing chemical compounds creates interesting reactions
It's exciting to participate
Green flubber
A very small flame...
Becomes a flaming tornado with the addition of air
Super flamable cotton balls
Agitating the compounds caused them to change color
Combining simple ingredients without stirring creates...
A long filament of nylon-like substance
More willing participants
Pouring super-cold liquid nitrogen on the floor creates a harmless cloud
Brother Thorn tops up the liquid nitrogen
You can't pound a rubber nail into a board unless...
You freeze it in liquid nitrogen
Then you can pound it into the board
Everybody who wanted got to shake the compounds
The air inside the balloon contracts when it is inserted into the cold nitrogen...
Causing the balloon to contract
As the air inside the balloon warms, it expands and the balloon fills again
Mixing these compounds made them go from clear to colorful and milky
If you heat the canister, put in the lid, cool it on ice, the air inside will contract...
And the very strong canister will crumple like a flimsy soda can
Elephant toothpaste
A shot of electricity creates "lightning" in the bottle, ignites the gas, and blows the cork sky-high
Mixing these compounds created luminescence
We were going to try the liquid nitrogen experiment if there was time;
sadly there wasn't, but the balloons were fun
Like we said: fun
We were able to visit with Jenn after the presentation
This was a great activity! Special thanks to Jenn Nielson and all who helped make it so much fun.
