This is a great group of toys and science experiments. Mostly bought at the science store on Oak Bay Ave and worth over 150$ new. Most are new in box. The volcano, balloon-powered boat and the rocket are gently used. Great for those rainy weekends that will soon be upon us! The IKEA tent is clean but one of the poles is not completely straight so I'll throw that in, too. From a non-smoking household. Please email if you have any questions. May be willing to break up the set. Must pick up.
