The frozen liver conundrum
You want to go frog trapping tonight, but the shop only sells frozen liver. You're already in the field, so what do you do?
Liver is a really useful bait for frogs in the genus Xenopus. Attracted by the meaty odours, the frogs will willingly come into a trap placed overnight into a ditch or pond. However, chicken livers are regularly sold frozen, and the frozen block is really hard to sparate and use.
Here you see Marius Burger finding a solution to this frozen liver problem. Although his first key idea was functional, it wasn't popular. The next solution is, I believe, unbeatable and one that we are ready to share with you. Moreover, this might be the first time that anyone has come up with such a practical and fast solution to the frozen liver conundrum.
Thanks Marius!
