abandoned bamboo stalk

I brought these 4 bamboo stalks . It is abandoned . There were  4 poor remaining bamboo stalks on the flower display . I felt them very pitiful . And they are going on discount on 1.50 per bunch . So I just purchase them without thinking . Brought a plastic container and some jelly stones . I left the jelly stones into the red jar overnight and then it become my 1st new plant I adopted in my office . The 4 up straight bamboo .May i had a life as upright as bamboo , things would be going upright like my bamboo , My career go straight up and up .
 hahahahaha...But there are abit yellowish . That is not healthy . Actually , they are wriggling when I  brought them somehow they did sprout some green bulbs . So maybe I should be happy .I hope after i spray the nutrition it will turn more greenish and prosperous .
