Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for schools in Cyprus. I have taught science for 20 years. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself. I also share and show some of these ideas at workshops, science conferences, or inservice presentations.

![How basilisk lizard walks on water!!!
The common basilisk, along with the other members of its genus, take the nickname the Jesus Christ lizard or Jesus lizard because when fleeing from predators, they gather sufficient momentum to run across the water for a brief distance while holding most of their body out of the water (similar to the biblical story of Jesus walking on water). Basilisks have large hind feet with scaly fringes on the sides of the third, fourth, and fifth toes. These are compressed against the toes when this lizard walks on land; but if it senses danger, it can jump into the water, opening up these fringes against the waters surface. This increases the surface area of the foot, thus allowing it to run on the water for short distances. This occurs in three steps. First is the slap, the downward movement of the foot that pushes water out and away from the leg. This also created pockets of air around the foot. Next is the stroke, the backwards movement of the foot, which propels it forward. Next is the recovery, when the foot comes up and out of the water and prepares to do the slap again. Smaller basilisks can run about (10–20) m without sinking.[citation needed] Juveniles can usually run farther than older basilisks, while holding more of their body above the water.
