local place to buy a few things

i need:
sulfur hexaflouride
sodium acetate (i would rather buy it than make it)
dry ice

i know of a few places for dry ice (irish) but was wondering what else was around.

for those whose interest i have piqued i have been doing science “experiments” with my kids to get their brains working and get them intersted in how and why things happen.

Hey Bill Nye, go get a liter of cola and pack of mentos, you nerd.

lol some of them are acutally really cool

Stop over, I actually have a sweet packet from school that has a ton of experiments in it. They have all the instructions and materials you need.
I will copy it at school.
