12-16mm Orbeez Balls Crystal Water Beads (2500 Pack)

These balls are commonly referred to as Orbeez but go by many names such as magic balls, water beads and crystal balls. They come in a variety of colours and only require water to enlarge many times their original size. Orbeez can be used by young children over the age of 5 years (no younger due to the choking hazard posed). They are commonly used in water pellet guns, but can also be used for decorative purposes or playtime in the bath. They are biodegradable (and can even be used as a method of releasing water slowly in plant pots). They are non-toxic and non-flammable, making them safe for you and your family! What size do the large size water beads enlarge into? The large size will grow to around 12-16mm in size, after being left in water for 5 to 6 hours. Which colours are available? Red Blue Yellow Purple Pink Orange Dark green Green Peach Gold Transparent White Black Mixed colours How are they made? This guide on Wikihow shows the procedure quite clearly (although they are using a slightly larger Orbeez size): https://www.wikihow.com/Make-Orbeez All you need to do is add roughly 240ml of warm water (warm water will result in the water beads growing at a faster rate) for every 100 or so of the balls. Then wait at least 5 hours and they will have grown to their full size! Safety notes: Not for children under the age of 5 years old. This product is a choking hazard for young children! The balls should be disposed of in the garden (where they will biodegrade over time, or put them into the trash). Do not put them down the drain as this may cause a blockage.
