Challenge 1. The children were playing the song 'Jingle Bells' on the boomwhackers.
Challenge 2. In the video, there were 24 children playing the boomwhakers.
Challenge 3. Boomwhackers make sound through air column resonance: when you strike a hollow plastic tube, it vibrates, causing the air inside to resonate at a specific frequency, producing a musical tone, with longer tubes creating lower notes and shorter tubes producing higher notes, all tuned by their length and color-coded for easy identification.
