How to brighten your mood in 5 min
Enjoy these three colorful, easy, and quick experiments with your family!
Warning! Only under adult supervision.
- stationery glue;
- tinted water;
- crayon nubs;
- silicone mold;
- fine sand;
- PVA glue;
- contact lens solution;
- baking soda;
- watercolors or gouache.
Mix PVA glue, watercolor or gouache paint, and contact lens solution. Add a little baking soda if necessary. When the mixture thickens, add a lot of fine sand and mix well – this makes kinetic sand!
Write something on a piece of paper with stationery glue, pour a large quantity of salt over it, and remove the excess. Use a pipette to apply tinted water – the words bloom with color!
Not sure what to do with your old crayon nubs? Fill a silicone mold with them and heat them in the oven – this creates new multicolored crayons!
The contact lens solution binds the glue molecules to each other. The resulting mass glues the grains of sand together, creating a kinetic sand that crumbles in your hands, but keeps its shape perfectly if you mold it into figurines!
Once they encounter the glue, the salt crystals leave many microchannels between them. Water fills them all, carrying the paint with it and decorating the inscription!
Wax consists of molecules that are relatively weakly attracted to each other. As a result, its melting point is only 40°C. Therefore, the wax crayons melt easily and form new ones!
