Noting promising preliminary data from Experiment 1 (#TumbleDrying) and previous work by @captaincretin suggesting #SpikyBalls agitation, Experiment 3a follows a baking power #wash with #Tumbling alongside a single 10 cm diameter #SpikyBall.
Outcomes are a significant improvement on the Experiment 3 baseline, lifting the #towel surface to a #thicker, #softer #nap, but there is insufficient data to yet distinguish the relative contributions of #HotAir and #Balls.
Further research is indicated.
