Learn about one of the world’s strangest plants.
The sandbox tree is a large tree that is native to South America. It can grow up to 40 meters tall in the right conditions. Their wide canopy of soft, thin leaves can also be inviting. However, it’s best to keep your distance because the sandbox tree can be quite dangerous.
The sandbox tree is covered in tiny spikes. These spiky thorns are a warning for humans and animals to stay away. The tree’s sap is also poisonous. In the past, native tribes in the Amazon rainforest used the sap to create poison for their arrows. In modern times, the sap has been used to make tear gas, which can temporarily cause blindness and breathing difficulties.
The danger doesn’t end there. The scariest part of the sandbox tree is its fruit. Though they look like tiny pumpkins, don’t let their appearance fool you. Once the fruit matures and falls from the tree, it becomes a ticking time bomb. When it dries, it will explode and shoot lots of tiny seeds at 250 kilometers per hour in all directions. This force can cause serious injuries to anyone nearby. This is why sandbox trees should never be planted anywhere near people.
