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.
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.
