Spring is finally here! - oops. never finished this post!

(At left) Mercer is VERY proud of these purple cups... they're called "speed stacks."  He bought them with his own money and stacks them / un-stacks them ALL the time.  It's something that a bunch of the kids at his school are doing.  It's sort of an obsession with everyone for some reason. 

These pictures (above) were taken at the Atlanta Science Festival at an exhibit at Emory University and the pics on the right from home in the "studio."  These were taken in late March on a rainy Sunday.  They never got posted.  Oops! So much for the (rainy) spring-is-here blog post~~

Mercer is playing with smoke from the liquid nitrogen that's being poured in the "instant" ice cream and he's doing a bit of human bowling on a plywood disk with a leaf blower attached to reduce friction.  

the COOLEST thing, however, was one of the Emory Students built a Reuben's Tube... it demonstrates sound waves pushing on compressed gas in a tube.  Light the flammable gas on fire and it's is a FASCINATING demonstration of a transverse wave in motion.  Enclosed is a direct link from the internet on this as my videos weren't as crisp (with Isabella crying in the background):  http://www.instructables.com/id/The-Rubens--Tube:-Soundwaves-in-Fire!/  (click on the video buttons to see the demo)

SCIENCE rocks~  :) 

In March, Mercer was named as "Master Agent First Class" in his Mission Possible Kids service organization that he belongs to at church.  Yay.  He's completed a lot of "missions."He's done so many positive things for other people in other countries (where the items they make and letters they write get shipped), in nursing homes (where taking field trips to deliver the items made & visiting in person), and even doing good for some folks in our church.  He has a lot of fun doing it and we are happy that he is serving others.
