During an extended family visit to the Hoge Veluwe natural reserve (where it rained the whole weekend so we barely ventured outside), Simon tried two things for the first time: bowling (fascinated by the terms spare, gutter, strike) and going down a waterslide. “This was the most amazing thing I’ve ever done in my life!” Simon told me afterwards about the waterslide, “I think it’s remain the only time I tried this though”, he added, as it was “too exciting”. He also told me how going down the slide inspired him to build a machine (using LittleBits) creating bubbles in the water and we fantasised about the design together.
