Discovery Mindblown Action Circuitry Electronic experiment kit

This is a pretty neat stem action set from Discovery. The age says 8+ but I think 6 or 7 with adult supervision is doable. My son enjoyed it. All parts originally in box included as well as booklet. Ill add in 2 AA batteries as well so it can be used fresh out the box. Disclaimer: fresh out the box, there was a battery metal component missing and the rocket didn't work even when using a working battery connector. All are included as well in case you have better luck. The other two experiments work great.
