A contact heat absorption fibers and water can easily grasp, and can be easily perceived by a simple work without soiling the hands exothermic heat absorption fibers, having a simple structure providing heating experience kit heat absorption fibers. An inner sealed bag-like object 2 having a weak seal portion 5 and the end portion is placed in A water 4, there a heat absorption fibers 3 in heating experience kit of outer sealed bag-like object 1 including the inside Te, by pressing the water inside a sealed bag-like object within 2 from the outside of the outer sealing bag-like object 1, and impelled water 4 of the inner sealed bag-like object 2 toward the weak seal portion 5 of the weak seal portion 5 sealing destroying, and is configured to allow the water 4 from the inner sealed bag-like product within 2 is contacted with heat absorption fibers 3 out. .FIELD 1【課題】吸湿発熱性繊維と水の接触が容易に把握することができ、かつ吸湿発熱性繊維の発熱性を手を汚さずに簡単な作業で容易に体感することができる、簡単な構造の吸湿発熱性繊維の発熱体感キットを提供する。【解決手段】水4を入れられかつ端部に弱シール部5を有する内側密封袋状物2と、吸湿発熱性繊維3とを内側に含む外側密封袋状物1からなる発熱体感キットであって、内側密封袋状物2内の水を外側密封袋状物1の外側から押すことによって、内側密封袋状物2の水4を弱シール部5の方に押しやって弱シール部5のシールを破壊し、内側密封袋状物2内から水4が出て吸湿発熱性繊維3と接触させることができるように構成されている。【選択図】図1
