Title: Density-based novelty toy samples

Description: These inexpensive and fun novelty toys show drop formation. Some incorporate wheels that turn as drops fall on them (first and second photos from left) and some have rails that guide falling drops (first and third photos from left). Another modification is an arrangement of rows of staggered obstacles through which drops pass (last photo from left). Watching drops deform as they navigate the obstacles is fascinating. In all these toys, immiscible and non-wetting liquids of different densities are used. For more information on these and other density novelty toys, contact Said Shakerin at sshakerin@pacific.edu.
