science and math fun fair

I really enjoy the math and science fun fair.It was fun playing with friends. I like the games especially tug of war and from trash to treasure which is picking up trash  and putting it in buckets and competing with friends. But unfortunately my group and I has to wait for 15 minutes to play almost all the games and it was really annoying thank you for reading this entri.

Inflating a balloon with vinegar with baking soda

                This are pictures of my group when we are inflating a ballon using vinegar and baking soda . I was quite nervous and thought that it wouldn't work but it actually works. Its really cool but because of the vinegar it stinks.And I am happy I get a inflated balloon attached to an aqua bottle that has a mixture of vinegar and baking soda which is pushing C02 to the balloon.
