zara and Finn Gadget Quest

Zara and Finn are exploring the floating Crystal Islands of Lumoria when Grox sends his Scraps to steal the Gravity Crystals — magical science stones that control how gravity works on each island. One by one the islands begin falling. Zara uses her LUMOGLOVE to scan the problem and explains gravity to the audience. Together they build a Gravity Cannon from Finn's TECHPACK to shoot the crystals back into place — but they need to calculate the right force and angle each time. In the end they outwit Grox, restore all the islands, and teach the audience everything they need to know about gravity.
