Hi Room 11! Today I rode a bicycle over a gap on the 3rd story of the California Science Centre on a high wire. Getting to do this was a surprise from my mum...she didn't tell me about it first. I felt a little nervous to begin with, but it was epic! To be honest, it did feel like it could tip off at any time. You were trusting counter balance to keep you steady. It worked, even though it did get a little wobbly . I rode across the gap 4 times, which was probably 40 meters. It goes smoother when you go a bit faster because the momentum projects you along. It was so cool! But I was glad there was a safety net #wink!
