Turn your home into a real laboratory! Everything you need is already in this secret box. Instructions: Wear gloves! Mix 2.5 grams of sodium alginate, a little dye, and 50 ml of warm water. Stir well. The reagent dissolves poorly, so try to... crush it and then leave it for 20 minutes for complete dissolution. In a separate container, prepare the second solution by mixing 5 g of calcium chloride in 50 ml of cold water. Be careful, the solution may heat up while mixing! Fill a syringe with the first gelatinous solution and squeeze the contents into the second solution. After 1-2 minutes, take out the resulting worm, do this while wearing gloves! Now you can play with it! Master real magic with "Eureka"! Open the box, dive into the world of chemistry, and conduct the experiment yourself. Create your own polymer worms and play with them!
