On offer are gallium spoon molds, these produce beautiful gallium spoons that can be used for in-class demonstration purposes (chemistry/physics etc.)
When stirred in hot water, the spoons melt at 29.8°C / 85.6 °F, to leave a stunned audience! Beats the age-old ice cube melting for melting point demonstrations!
The liquid puddle can then be solidified by cooling, and the solidified lump can be used to forge new spoons over and over! Also on offer is gallium metal to make your spoons.
