5Sandbox Tree (Hura crepitans)

The Sandbox Tree, also called the “Dynamite Tree,” is native to tropical regions of the Americas. This tree has spiny bark and toxic sap that can cause severe skin irritation and blindness if it gets into the eyes.
The nickname “Dynamite Tree” comes from its explosive seed pods, which burst open with a loud bang, sending seeds flying at high speeds. These flying seeds can cause injuries, making the Sandbox Tree doubly dangerous.
