How to Make Zero Gravity Toys

When I was a kid, we used to play with all sorts of made-up toys, including some that appeared to defy gravity, at least for a while.
My favorite was a helium-filled balloon onto which we attached paper clips. Simply slide the first paper clip through the knot in the balloon holding the helium inside the balloon, and add paper clips as counterweights until the balloon floats at whatever height you designate. The more counterweight (paper clips), the lower to the ground the balloon will rest. The fewer paper clips, the higher it will fly.
The best part was finding how many paper clips it took to create an equilibrium between the lift of the helium in the balloon and the counterweight needed to keep it about face level.
The fish are fun too, especially when you get to name them things like "Swimmy."
As for kites, they're less fun to name, but if it makes you happy, go right ahead.

Instructions

  1. Filling the balloons with helium

    • 1

      If you plan on making a room full of balloons (always a personal favorite, but one balloon will do), you need either prebought helium-filled balloons or a rented canister of helium from a local party rental store.
      Though they are a little more expensive, the foil type of balloons hold their helium for up to five times longer than do plastic balloons. Once the balloons are filled with helium and fastened shut, by either knot or string, you're ready for the fun part.

      First, collect any balloons that have made it to the ceiling.
      Then you have three options.
      You can either leave enough string on the balloons to serve as a counterweight, attach paper clips or use a combination of the two.

    • 3

      Either trim the string (a little at a time) or add the paper clips (one at a time) until the desired equilibrium is achieved.
      If you set the heights differently and there is a roomful of balloons, it's almost like walking through a colorful water lily bog. If they are set to float a little above your head, it's like walking through vine tendrils in the Amazon forest. But set them as you like. They are your toys, and it is your playtime.

      As the helium escapes the balloon over the course of days, as it inevitably will, simply remove paper clips or trim the string (remember, a little at a time) as necessary, to restore equilibrium.

    Balsa wood fish

    • 5

      For this fun toy, you need some small pieces of balsa wood, an X-acto knife (to shape your fish), airplane paint, a clear shellac or polyurethane, a very thin brush, a spool of low gauge wire, small lead shot (the kind you would put on your line when fishing) and a pair of needle-nose pliers. You'll also need a small clear fish bowl, kind of like the ones you win at carnivals when you throw a Ping-Pong ball into one of the bowls. Unlike carnival fish, these fish don't die the next day.

    • 6

      First, cut out your fish.
      They don't even have to look like fish. Make them dinosaurs if you want. Next, paint your fish. Give 'em smiles, frowns, stripes, polka dots, horns. Heck, give them hair and make them look like your schoolteacher. Whatever.

    • 7

      After the paint dries, paint a thin coat of shellac on the fish so water won't seep into the wood.

    • 8

      When the shellac has dried, cut a short piece of wire---about a quarter to half inch---and form it into a U shape with the pliers. Push both ends of the U into the bottom of the fish, and put it in a clear fish tank filled with water. See where it floats, and then add split shot until it floats at the desired water depth.
      Presto! You now have a pond of fish that you'll never have to feed (and that won't die).

    Let's go fly a kite

    • 9

      Save up a few dollars and buy a kite.

    • 10

      Follow the instructions on how to assemble the kite.

    • 11

      Find an open area free of overhead obstacles such as trees and power lines, and wait for the wind
