who knew....

science is fun

this summer we have been doing a lot of different experiments
nothing too fancy or crazy, but just enough
to have a little fun

what boy or kid, for that matter, on this planet doesn't like a little explosive mess now and then?

Nathan LOVED these exploding bag bombs.


I swear we have been buying out the local store of vinegar and baking soda this summer  haha.

All you need for these bags is



a paper towel or toilet paper
 (we found that the toilet paper works faster, less absorbent I guess)
2 TBS baking soda
1 cup vinegar
zip lock baggie
warm water
food coloring
(optional...and a lot more fun)

place the baking soda on the toilet paper 


and roll it up to make a little packet


pour vinegar into the baggie and add just enough warm water to make the bag more than half full
add food coloring, if so desired.



next, head outside
(trust me, you don't want this mess in your house)

once you are outside, place the baking soda packet in the baggie
quickly - yeah, you better move fast - zip up the bag and place it on the ground

and

..................................

BAM


our's started exploding and overflowing before it even hit the ground.



Nate's favorite one was the red one - he said it looked like blood and guts hahah - boys!

how it works:

baking soda and vinegar mixed together starts a chemical reaction that makes carbon dioxide.  the gas bubbles up to the surface of the liquid and then fills the top of the bag.
the pressure from the gas builds up and when there is nowhere else for the gas to go, the bag bursts open and the gas escapes.

fun stuff!
