1、取6根冰棍棒，三根一组，分别粘成等边三角形。
2、剩下的2个冰棍棒端切出一个60度斜角，另一端钻一个小孔，孔的大小够细绳穿过即可。
3、将带小孔的冰棍棒分别粘在两个等边角形上，一根粘在边的中点，一根粘在角平分线上。
4、要制作张力平衡结构,还需要4根细线,将两个冰棍棒架子相对凑在一起，量一下两角之间的距离，大概是10厘米，因此边上的细线长度就是10厘米。
5、剪3条略长于10厘米的细线，分别固定在2组支架相对的角上，角之间的细线长度需确保是10厘米。
6、将2组支架上下相对放置，剪1条细线，先穿过下方的A孔，固定好，再穿过上方的B孔，拉紧，使得边角上的三条线都能伸直紧绷，然后绑紧固定住即可。
7、这样一个张力平衡结构就做好了。用4根细线，让两个看似重量大得多的冰棍棒支架可以悬空站立。
制作张力平衡结构支架所需材料和工具: 8根长短相同的冰棍棒、细线、美工刀、尺子、铅笔、热熔胶枪、钉子或手电钻。
反重力是一个物体被另一个物体排斥的引力式的力。不论是牛顿的还是爱因斯坦的引力论都没有排除负质量的存在，这种质量将排斥平常（正）的质量。反重力的观念是以负质量的设想为基础的。到1968年为止，还没有人报道过观察到支持这种设想的证据。
