CrashPals
A crash lab for ages 6–8: two carts roll toward each other and clink together. Guess which way they roll after they bump — left, stop, or right — then watch! Chug the marmot shows the big idea: the cart with more push (how big × how fast) decides which way. On-device; nothing leaves your device.
#0e7490 Distributed-narrative cast
Meet the cast
CrashPals has a tiny friendly crew who make force & motion something a six-year-old can hold: Chug the marmot runs the Bump Lab and asks you to guess before every bump; Hefty the bear pushes a big heavy cart and pushes hard even when he rolls slowly; Nippy the hare pushes a little cart and pushes hard because she zips along fast; and Clink the cricket links two carts when they meet, so they couple together and roll as one. Each friend shows ONE gentle idea about the push; everything is spoken, and there is no way to lose.
Chug
(Guide) Chug the marmot who runs the Bump Lab - counts the push (how big x how fast) and asks you to guess before every bump

Hefty
Hefty the bear - pushes a big heavy cart, so pushes hard even when slow, because being BIG adds to the push (mass)
Read chapter →
Nippy
Nippy the hare - pushes a little cart, so pushes hard even when small, because being FAST adds to the push (speed)
Read chapter →
Clink
Clink the cricket - the coupler: when two carts bump he links them so they clink together and roll as one (the pushes add up)
