For their afternoon challenge, “Thith Meanth War!”, the AcadeCoders had to combine control flow with a few new Ruby string methods to Daffy Duckify a user’s string, replacing each “s” with “th”.

Following lunch, the AcadeCoders took time off their computers their afternoon activity! We usually head for Morrison Park for outdoor activities and free-play, but the rainy weather said otherwise. The indoor activity was Speed Stacks and the AcadeCoders were put in singles and doubles tournaments to see who has the fastest time to stack up and stack down speed cups.
