Today we opened our test tube alien by the name of Zog. There were certain instructions on how to hatch the thing for it was in a white bumpy looking cocoon. Myself and J.B. were in charge of hatching it. We followed the instructions where it said to 'keep on adding water to the alien through the feeding hatch until all the fizzing stops'. This took a lot of water but in the end we hatched it. Now it was time to clean all the residue of the left over cocoon. Movies and I went outside to the tap and cleaned it all out by refilling and emptying the tube a few times. It was now ready for feeding. To do that we added the dehydrated 'sloog' to 150 ml of water and stirred it around in the cup. He needs 12 hours daylight and 12 hours of darkness. Everyone in the class had a quick turn in the feeding it with a teaspoon. He is now in the office satisfied, safe and sound.
Signals
On top of Zog's head is a light. This is where his heart is. When he is feeling hungry it flashes orange. When he feels that everything in his environment is right, it flashes red. When it flashes green, he is drowning.
How it Works
Zog's body contains a substance called polyacrylamide which is a type of polymer. This soaks up water which causes it to react to grow big. This is eight times it's original size. The 'sloog' contains a weak acid which slows the growth down to make it seems it is growing over several days.
I think that we will have a great time knowing the alien but I hope he doesn't die until the big school holidays!
The fizzing...
almost there...
and the final product.
