Wonder Blocks

Place a red, a white, & a blue block into the tube, in that order. Then tip the tube to let the blocks out the other end, & the red one is now in the middle! You can repeat it, & again the blocks will change places INSIDE the tube, & the red will be in the middle! Finally, you can put two blocks into the tube, put the third one in your pocket, & instantly all three blocks are back in the tube! Ages 6+
