The present invention relates to a channel fracturing method with alternative injection of conventional and capsule-type soluble proppants. The method includes the following steps: injecting pad fluid into a wellbore to break a formation and form fractures in the formation; alternately injecting a sand-carrying fluid containing conventional proppant and a sand-carrying fluid containing capsule-type soluble proppant into the wellbore in sequence to support fractures in the formation and continue to fracture the formation; injecting displacement fluid into the wellbore to completely displace the sand-carrying fluids in the wellbore into the fractures. The conventional proppant of less dosage is used. The capsule-type soluble proppant is less difficult to be developed and its solubility is sensitive to the fracture closure, which is conducive to the quick flowback after fracturing. The channel fracturing technology is more mature, reliable, and cost-effective, and the concept of forming high-conductivity channel is more simple and effective.

A water and bubble toy includes a water projecting assembly and a bubble generating assembly. Water is stored in a water reservoir located in a rear handle of the toy while bubble solution is stored in a detachable reservoir. The water generating assembly is operated by a lever located toward an upper end of the toy. When the lever is pulled, the lever activates a first pump that expels water from the toy. The bubble generating assembly is operated by a finger trigger that activates an electric motor, which powers a second pump and a fan. The second pump pumps bubble solution to a ring and the bubble solution coats the ring. The fan blows air through the ring and helps generate and propel bubbles from the ring.
