R Exclusive, only available at Toys R Us Canada. Kids will go wild for the Ryan's World Cool Chemistry set. This exciting set contains everything you need for 4 hair-raising experiments. Just like Ryan, you can grow your own beautiful crystalline stalagmites and stalactites (how do you remember which one hangs from above and which one grows upwards?). Budding scientists can learn how even the most mundane of activities like making a cup of tea is actually science with the fantastic filtration experiment. Observe vibrant red moving molecules, watch distinctive diffusion and create colourful chromatography to wow your family and friends! You can also discover the pH of substances and create a simple lava lamp by using an everyday water bottle you'd find at home. Includes 16 page educational booklet. STEM benefits: science and maths. Suitable for age 8+
