超甜特技！自己動手打造口香糖球機，同時學習物理原理。轉動把手，每次從透明儲存球中釋放一顆口香糖球，沿著軌道滑下。口香糖球會落入收集杯中，並可衛生地放回球體再次運行。軌道段可在底座上移動，創造出幾乎無限數量的不同口香糖球機。當口香糖球沿軌道滾動時，會表演酷炫的特技與技巧。特技包括滑輪升降、鐘擺、漏斗、彈跳床、可變坡度斜坡、彈珠發射器及骨牌滑梯。每個軌道段教授不同的機械物理課程，讓使用者探索簡單機械、力、運動、動量、重力、牛頓定律、能量轉換等主題。
透過試誤實驗，以有趣且動手操作的方式學習：您的口香糖球能否成功抵達軌道終點？還是需要重新設計口香糖球機才能運作？此套件適用標準機器尺寸的16公釐（5/8英寸）口香糖球，並附贈少量口香糖球供您開始使用。

The clear globe is perfect for seeing exactly how many gumballs you've got left, and that satisfying clunk when it dispenses one at a time never gets old. My nephew figured out the track alignment himself in about ten minutes, and now he's explaining the physics to his little sister.
Watching my kids take turns cranking the handle and seeing exactly one gumball roll down the clear track is oddly satisfying — it’s real physics they can see. The globe holds plenty, and the lesson on gravity clicked way faster than any textbook.
The clear globe is a nice touch—you can watch each gumball roll down the track, which my kids found way more entertaining than I expected. Assembly took us about an hour together, and the handle turns smoothly enough for a plastic kit, though I wish the instructions were a bit clearer on one step.
