Our crystal follow up

Now our crystals are bigger than before. you can really start to see the crystals. This worked because the salt clings on to the wool as the water evaporated.. It didn't form on the pipe cleaner because the pipe cleaner is made out of wire.
Lots of us trout that we were going to grow big expensive crystals, boy were they wrong!!
These are our photos of our crystals now
