Has anyone else had luck with a good method to remove the crystal starter? I can't get them out without the crystals literally crumbling.

It does not pop out easily... it's really hard and when you try the entire crystal shatters. Huge disappointment.

Do I need to buy additional items for this, or are all supplies in the kit?

Hello,This kit does come with everything that you will need for this experiment (except the heated water to add to the crystals)! Thank you for your inquiry,MeganNational Geographic Toys Customer Support

Is this good for a 12 year old?

I am not sure.. I would think so .. I got it for my 9 year old grandson for Christmas this year. He lives anything to do with crystals

does the power support 220v for Europe ?

You can get a little converter for 220v at an electronics or travel store.
