अगदी हसत खेळत व ताण-तणाव बाजूला ठेवून मुलांना विज्ञानाचे शिक्षण देता देता विज्ञानातले सिद्धांतही माहित करून देण्याच्या उद्देशाने श्री. डी.एस.इटोकर यांनी या पुस्तकाची रचना केली आहे.
विज्ञानविषयक सुमारे पन्नास खेळणी स्वतः तयार करून त्यांच्याबरोबर खेळणे व मित्रांना दाखविणे यात मुलांना आनंद तर मिळेलच, पण त्याचबरोबर त्यांच्या विज्ञानविषयक ज्ञानात भर पडून विज्ञानाची अभिरुचीही वृद्धिंगत होईल.
