~~you should try this at home!~~

a few days back we tried a very cool experiment. almost every day since, the children have been begging to do it again! after collecting water bottles, balloons, a funnel, vinegar (acid) and baking soda (base), we prepared by pouring the acid into the bottles to 1/2 full and 2 heaping tablespoons of the base into each balloon.


standing ready.... set....


MIX!!!
(the results were instant... perfect for eager, curious budding scientists)


the balloon expanded until some of the pressure was released through the valve at the bottle.


i think we were all amazed at how simple and fun this could be!


we found that remixing the solution encouraged the reaction.
