"I chanced upon a couple of seed pods during my daily early morning stroll along the banks of the Siem Reap River. They looked like exquisitely carved miniature pumpkins; nature’s very own decorative art, so I took them home and placed them on a shelf in my apartment. This was not a move welcomed by Khmer True Love. She took a more derisive approach, regarding the seeds as mere junk that had no place in the home, and muttered at length about the inherent craziness of barangs. Then, in the wee hours of the morning, the first of the pods dynamically exploded, followed by the sounds of crashing glass and the clatter of falling wood. It sounded like a gun had been fired in the room, and the shrapnel from the exploding pod blew away items on the shelf including blown glass figurines from Battambang."
"Khmer True Love awoke and screamed. I jumped from bed and hopped about in a panic until I realised we weren’t the victims of a home invasion.
It gradually became evident that the pod was the villain. Khmer True Love was far from happy, but we both settled down to regain sleep when “Bang!” – the second seed pod went off to even more dramatic effect."http://www.phnompenhpost.com/siem-reap- ... -riverbank
"the fruit of the Sandbox tree will explode like a botanical hand-grenade carrying seeds up to 40m at 240kph, easily penetrating any animal or poorly placed window."http://www.unbelievable-facts.com/2013/ ... whose.html
"For sheer ballistic verve, we look to another tropical plant, one that is also cultivated in South Florida. It is Hura crepitans, the sandbox tree of the Euphorbiaceae. It has capsules the size and shape of tangerines. Each fruit has many segments, just as does a tangerine, and each fruit segment contains a seed the size of a nickel. When the fruits burst open, they shoot their seeds nearly 150 feet, accompanied by an explosive noise that is said to sound like the discharge of a rifle!"http://www.virtualherbarium.org/gardenv ... istic.htmlhttps://www.youtube.com/watch?v=x_OAS-K0feI
"They are among the largest trees of tropical America and are interesting for their pumpkin-shaped seed capsules that explode with a loud report, scattering the seeds. Sandbox trees are sometimes grown as boulevard trees but have disadvantages in their poisonous leaves, bark, and seeds and the explosions of their capsules, which have force enough to injure persons or livestock."http://www.britannica.com/plant/sandbox-tree
"Angular velocities are high, attaining at least 15,000 rpm in one case." It's fruit are used to make wheels for children's toys."http://onlinelibrary.wiley.com/doi/10.1 ... x/abstracthttp://onlinelibrary.wiley.com/doi/10.1 ... 174.x/epdf
