The toys that work with heat using the basic principles of energy transformation through various processes or reactions based on physics and chemistry.
Science and technology have made great advances in energy matters to contribute to the development of the human being.
Through the different types of energies existing in the world, technology has evolved and has developed high quality devices, machines and tools.
Contributions have been made both in devices used at home or in industry, as well as in the field of toy manufacturing.
Technology currently contributes to children and adolescents, giving them the possibility of enjoying a wide variety of options that use energy transformation processes. With this they create fun objects that are useful for learning.
The 5 toys that work with heat
1- Cars that change color on contact with hot water
Companies that are at the forefront of toy race car and track manufacturing are always innovating to keep kids interested in their products.
Currently they have created pieces that change color on contact with warm or hot water.
These manufacturers use the principles of thermochemistry. The paint on the toy, when it comes into contact with warm or hot water, produces an endothermic reaction that generates a color change.
2- Dolls that change color when submerged in water
Innovation in toy manufacturing encompasses the doll industry. Manufacturers have presented countless models of dolls whose costumes change color when immersed in warm or hot water.
The principle used by manufacturers is the same as in the previous case. The paint present in the fabrics of the fabrics alters on contact with heat and an exothermic reaction is generated. This reaction happens when the fabric dries.
3- Solar robot that transforms into different objects
Alternative, clean and renewable energy is also used to make toys, such as this robot that can transform into six different toys, each with movement and free from the use of batteries.
The toy manufacturers added photovoltaic cells to the model, with which they transform the sun's radiation to generate the electricity required by the motors that generate the movement.
4- Wooden planes that move their propellers
The classic wooden toy was modernized. For this, manufacturers incorporate solar panels and motors into the traditional design.
These devices are strategically located so that the toy does not lose its old characteristics.
Solar panels capture light and heat to generate the energy needed to drive the propellers.
5- Steam robot
These toys are out of the ordinary. They can become collectible and not suitable for children.
These run on steam and some use coal, like trains from centuries past.
To generate steam and motion they use the basic principles of the laws of thermodynamics.
