a) Increasing the temperature of the solution
b) Adding ethanol, methanol or other alcohols
Small insects such can walk on water because their weight is not enough to penetrate the surface. A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, needle will quickly sink.
A water skipper is able to walk on water based on surface tension.

A little dish detergent will help break the surface tension.
Living things use surface tension to walk on water, by distributing their weight across the water's surface without breaking it. Some insects, like water striders, have adapted to take advantage of surface tension to move and survive on water. They also use it to trap and consume prey, by secreting sticky substances that immobilize their target.
Surface tension can support the weight of small creatures such as water striders or insects that are lightweight and have specialized adaptations like long legs. Larger animals may not be able to use surface tension to walk on water due to their weight exceeding the surface tension's ability to support them.
Insects use surface tension to walk on water and other liquids. The surface tension of water allows insects to stay on the surface without sinking, helping them move around and find food or mates.
The method usually fits into one of two general categories: 1). Use the formula that has been developed for the surface area of that particular shape. 2). Break the shape down into pieces with shapes for which the formula for the surface area has been previously developed, and then apply the method of Category #1.
Yes, fleas can be drowned. The most effective method for drowning fleas is to use a solution of water and dish soap. The soap breaks the surface tension of the water, causing the fleas to sink and drown.
The independent variable when building a raft powered by surface tension would be the raft design or materials used. By changing these factors, you can observe how they affect the ability of the raft to float and move on the water surface due to surface tension.
There are several insects that can walk on water due to the water's surface tension. There are over 300 species of water striders that are able to walk on water, as well as several species of ant.
"Many of these insects are adapted to utilize the surface tension of water for locomotion. The surface tension of water makes it possible for some insects to stand on water and remain dry."
