Vortex Maker x 2
Vortex Maker - 2 pieces
2 plastic vortex makers. These fun vortex makers simply screw into (and join) two soft drink bottle ends to produce a wonderful demonstration of how a vortex work. A great addition to the science table. Children love swirling the bottles until a vortex occurs. Soft drink bottles are not included.
Not suitable for children under 3 due to a choking hazard.
