POVZETEK

Gravity! What Goes Up, must come down and Peadar investigates this on the largest Rollercoaster in the county. His helpers in studio Freddie Ní hAlmháin and Liam Ó Fátharta help him to figure out the centre of gravity using a hammer and ruler and they also get to design miniature parachutes for a head to head challenge. Úna visits athletes at a trampoline centre and An t-Ollamh Ullamh gets quite the bump on the head in his endeavours to teach Aodh all there is to know about gravity!
