Well, a naked egg is an egg without its shell, of course! After this week-long experiment (yes, a lot of patience and waiting is required), you’ll get a rubbery, soft, somewhat bouncy egg. It’s pretty weird and the kids will definitely be amazed!
What you need • An egg • Tall glass • Vinegar
What to do 1. Gently place the egg in the glass and pour in vinegar until it is completely submerged.
2. Leave the egg in the vinegar for 24 hours. You’ll notice bubbles forming on the shell.
3. After a full 24 hours, change the vinegar. Pour the old vinegar away (careful with the egg) and fill the glass with new vinegar.
4. Keep your experiment away in a safe place for seven days. While waiting during the next few days, do not disturb the egg!
5. After a week, slowly pour the vinegar away and carefully rinse the egg with water. Tadah – you have your naked egg!
Everyone knows lava lamps are ultra cool. You just need one of these things in your room and voila, it automatically gives it a different vibe. So how bout’ making one from scratch?
What you need • Clean, plastic soda bottle, glass or jar • Soda bottle cap • Vegetable oil (the cheaper the better) • Food colouring (choose your favourite colour) • Alka-Seltzer tablet or fizzy tablets • Big flashlight • Water
What to do 1. Fill the bottle or container 3/4 full with vegetable oil. 2. Fill the rest of the bottle or container with water (almost to the top but not overflowing). 3. Add about 10 drops of food colouring. Make sure the water turns fairly dark in colour. 4. Divide the Alka-Seltzer tablet into eight pieces. 5. Drop one of the pieces of Alka-Seltzer into the oil and water mixture. Watch what happens. 6. When the bubbling stops, add another chunk of Alka-Seltzer. Observe further. 7. If you want to make it even more "lava-like" place your bottle or container on top of a huge flashlight and turn the room lights off. 8. When you have used up all of the Alka-Seltzer tablets and when the bubbling has completely stopped, screw on the soda bottle cap (or container cap). You now have your own lava lamp!

What to do 1. Spread the Rice Krispies out on the table surface. 2. Put the wooden blocks or other non-conductive materials on the table, and balance the plate of plexiglas over the table and the pile of Rice Krispies. 3. Vigorously rub the top of the plexiglas with the wool sweater. Presenting the jumping Rice Krispies!
Do you have any idea how easy it is to make your own glue out of simple ingredients such as milk, vinegar and baking soda?
What you need • Mixing spoon • Cheesecloth • 2 small paper drinking cups • 1/4 cup milk • 1 tablespoon white vinegar • Baking soda (just a pinch)
What to do 1. Pour the milk into one of the paper cups. Add the vinegar and stir for one minute. The mixture will form clumps (curds) and clear liquid (whey).
2. Place the cheesecloth over the second cup and push the middle down a bit.
3. Holding the cheesecloth in place, slowly pour the curds and whey into the cloth. Most of the whey will flow through the cloth into the cup. Gently squeeze the rest of the whey into the cup and then throw the liquid whey away.
4. Scrape the curds into the empty cup. Add the pinch of baking soda and stir well. You've got glue!
