Experiment kit by Walter Kraul GmbH
From invisible to spectacular: discover the fascinating phenomenon of vortices!
Vortices are all around us – in the kitchen, in the garden, when flying or even in space. Yet they often remain invisible. With the “Wirbel in Wasser und Luft” experiment set from Kraul, these impressive natural phenomena are made visible and tangible – playfully, creatively and with many aha moments.
Whether delicate smoke swirls after blowing out a candle or powerful whirlpools in water – with incense cones, dyes, straws, table tennis balls and other clever materials, vortex rings, vortex streets, circular vortices and even funnel vortices can be created and observed. In a richly illustrated instruction booklet, the phenomena in air and water are compared and explained in an easily understandable way.
What can be discovered with this set:
* Making air vortices visible with smoke
* Observing water movements with drops of dye
* Distinguishing between laminar and turbulent flows
* Building your own rubber-band paddle-wheel boat & vortex mobile
* Physical effects such as resistance, suction, waves and rotation
* Observations in everyday life, nature and even in space!
Learning by experiencing – very much in the spirit of the four elements:
This set invites children from 10 years to understand natural science through play – with air, water, earth and fire as the foundation. It encourages curiosity, powers of observation and a deeper understanding of the physical processes around us.
